Munich railway station shooting leaves several wounded

A number of people, including a female police officer, have been wounded after shots were fired at a railway station in Munich.

The police officer was shot in the head after a man grabbed her pistol and then fired at bystanders at the Unterfohring underground station.

Police said the officer's injuries are life-threatening but injuries to members of the public were less serious.

The incident is not believed to be terror-related and the suspect was detained after officers shot him.

Police spokesman Michael Riehlein said the area had been secured and there was no danger to the public.

Another police spokesman added: "The sole male perpetrator was motivated by personal reasons. There is no political or religious background here."

Police were called to the station following reports of an altercation involving passengers on a train.

When officers arrived the suspect tried to push them onto the tracks and then manged to grab the female officer's gun, police said.

London Eye owner sees terror impact on visitor numbers

The company behind some of Britain's biggest tourist attractions including Madame Tussauds and the London Eye said visitor numbers had been affected by recent terrorist incidents.

Merlin Entertainments said its London division saw a "softer domestic, day-trip market" after the Westminster attack in March with a "further deterioration" after those in Manchester and at London Bridge.

Shares fell 3%.

The company also said a number of its UK theme parks - which include Legoland, Chessington, Alton Towers and Thorpe Park - had been "adversely affected in recent weeks by the terror attacks and subsequent heightened security measures".

However, Merlin also said that visits by foreign tourists to its London sites had been boosted by the weakness of the pound - making their holidays to the UK cheaper.

It said this had continued in the immediate aftermath to the Westminster attack.

But the company was "cautious on trends in foreign visitation over the coming months" since the impact of the terror incidents would take time to filter through to holiday bookings.

Merlin chief executive Nick Varney said: "The impact of recent terror attacks on our London attractions is unclear at this stage.

"What is clear however is that London has bounced back before, and will do again.

"I have every confidence in the long term resilience and growth trajectory of the market.

"London is very much open for business, welcoming visitors from the UK and from around the world to this exciting and vibrant city."

Merlin, which operates more than 100 attractions around the world, earlier this year reported a 17% rise in annual profits, helped by the collapses in the pound after the Brexit vote.

Its wider performance has been overshadowed over the last couple of years by the crash on its Smiler ride at Alton Towers in June 2015 that resulted in a number of serious injuries.

Merlin was fined £5m over the incident last September.

Facebook, Twitter and YouTube face fines for allowing 'evil' online extremism

Facebook, Twitter and YouTube could be slapped with multimillion-pound fines for failing to remove extremist and criminal content under plans by the UK and France.

Online radicalisation will be a top priority during the Prime Minister's visit to Paris on Tuesday, in which she will hold talks with new President Emmanuel Macron.

As part of new laws to be drawn up by the two leaders, tech giants face being hit with large financial penalties if they allow unacceptable content such as terrorist propaganda.

:: Analysis - Tension between May and Facebook over online extremism

Mrs May's first foreign trip since losing her majority at the General Election will not be the triumphant outing on the world stage that Downing Street will have envisioned - and she is likely to face ongoing questions publicly and privately about what a hung parliament will mean for Brexit and her leadership.

But ahead of the summit, Mrs May said the joint campaign would "ensure that the internet cannot be used as a safe space for terrorists and criminals".

Last month, in the wake of the suicide bomb in Manchester, leaders of the G7 states - the US, UK, Canada, Japan, France, Germany and Italy - agreed a package of measures to step up pressure on firms such as Google and Facebook to take down "harmful" content.

Speaking ahead of her visit to Paris, the Prime Minister said: "The counter-terrorism co-operation between British and French intelligence agencies is already strong, but President Macron and I agree that more should be done to tackle the terrorist threat online.

"In the UK we are already working with social media companies to halt the spread of extremist material and poisonous propaganda that is warping young minds.

"And today I can announce that the UK and France will work together to encourage corporations to do more and abide by their social responsibility to step up their efforts to remove harmful content from their networks, including exploring the possibility of creating a new legal liability for tech companies if they fail to remove unacceptable content.

"We are united in our total condemnation of terrorism and our commitment to stamp out this evil."

The governments of Britain and France will not just punish firms, but vow to lead joint work with the tech companies to develop tools to identify and remove harmful material automatically.

Home Secretary Amber Rudd will meet her French counterpart in the coming weeks to develop the plans.

A recent report by MPs said the companies were not doing enough to remove extremist content online which may be fuelling hate crimes.

The Home Affairs Select Committee pointed out that in Germany, the justice ministry was drawing up plans to levy fines of up to €50m for firms which did not remove illegal content.

Theresa May to hold crunch talks with DUP leader Arlene Foster

Theresa May will meet the DUP leader Arlene Foster later, whose support the PM will need in order to get her Queen's Speech passed through Parliament.

It comes after the Prime Minister apologised to her MPs for the election result, telling them: "I got us into this mess and I will get us out of it."

The first move in Mrs May's new reality of compromise politics is to listen to what the DUP hope to gain by offering the Conservatives their support.

It is thought the Prime Minister is preparing to ditch unpopular policies such as her social care reforms and plans to means test the winter fuel allowance.

Arlene Foster said her party wants to "support the national interest" and "bring stability to the nation".

She told Sky News: "We enter these talks in a positive fashion, we are first and foremost unionists and therefore we want to secure the union.

Trump analytics firm Cambridge Analytica denies helping Leave.EU campaign

The chief executive of Cambridge Analytica (CA), the controversial data analytics firm which worked for Donald Trump's presidential campaign, has denied his company helped the Leave.EU campaign, saying it had been the subject of politically motivated attacks.

Cambridge Analytica is at the centre of an investigation by the Information Commissioner's Office (ICO) into the use of personal data by political parties, along with other companies.

Speaking exclusively to Sky News, Alexander Nix said that laws around data sharing would need to be changed, to keep up with current practice. He also said that the Conservatives had run an "ill-prepared" and "absurd" digital campaign.

He said: "A lot of the media that has been attacking us is liberalish, which means that they're pushing their own ideologies into print. Which is not very objective."

Over a series of articles, the Observer alleged that Cambridge Analytica had worked with the Leave.EU campaign during the Brexit referendum last year, but Leave.EU had failed to declare their contribution.

Cambridge Analytica has taken legal action over those articles.

Mr Nix told Sky News: "We've really been quite consistent to explaining to your colleagues in the press over very many months that we didn't work for any of the campaigns that were involved in Brexit."

I asked Mr Nix about an article he wrote for Campaign magazine, in February 2015, in which he said CA had "supercharged" Leave.EU's social media outreach.

"Yeah, look, that was an example of the cart pulling the horse, unfortunately.

"That was a press release written by a slightly over zealous PR adviser that was put out ahead of any work commencing with Leave.EU. At the moment that came to our attention, we were very quick to clarify that it was an error."

An article on Leave.EU's website, dated November 2015 but since removed, said that they "had hired the best people in the world" and that Cambridge Analytica "will be helping us map the British electorate and what they believe in".

Mr Nix dismissed the article.

"This doesn't say we worked with them. This document says that we might be working with them. And that was the case, we did have a number of discussions with them.

"We viewed different options with different campaigns about working on the referendum and we decided that we weren't going to work on it and we didn't work on it."

In February 2016, Andy Wigmore, the communications director of Leave.EU, told the Observer that Cambridge Analytica had been "happy to help" Leave.EU.

Mr Nix told Sky News: "I think you'd have to speak to Andy about that. But I understand that since that interview, he's changed his position and I believe there was some confusion about our company and another that he had been working with or talking about working with."

Mr Wigmore told Sky News: "CA did zero paid work for us - it was a simple pitch process and set-up. If we won designation we would use them [CA]. It's that simple. We did not win so did not use them.

"It's true that we have strong relationships with many involved with CA and it's true we were involved with many other campaign organisations involved with the Trump campaign which is how we were initially introduced to CA."

Talking about the ICO investigation, Mr Nix told Sky News: "They clearly feel that they need educating at this point. This is a very fast moving space and I think it's important that policy makers are up to speed with all the changes that are happening.

"I've no doubt that as technologies improve and data becomes increasingly available, that legislation will have to be adapted."

President Trump, alleging breach of constitutional oath

Attorneys general for the District of Columbia and the state of Maryland say they will sue President Trump on Monday, alleging that he has violated anti-corruption clauses in the Constitution by accepting millions in payments and benefits from foreign governments since moving into the White House.

The lawsuit, the first of its kind brought by government entities, centers on the fact that Trump chose to retain ownership of his company when he became president. Trump said in January that he was shifting his business assets into a trust managed by his sons to eliminate potential conflicts of interests.

But D.C. Attorney General Karl A. Racine (D) and Maryland Attorney General Brian E. Frosh (D) say Trump has broken many promises to keep separate his public duties and private business interests. For one, his son Eric Trump has said the president would continue to receive regular updates about his company’s financial health.

The lawsuit, a signed copy of which Racine and Frosh provided to The Washington Post on Sunday night, alleges “unprecedented constitutional violations” by Trump. The suit says Trump’s continued ownership of a global business empire has rendered the president “deeply enmeshed with a legion of foreign and domestic government actors” and has undermined the integrity of the U.S. political system.

“Fundamental to a President’s fidelity to [faithfully execute his oath of office] is the Constitution’s demand that the President ... disentangle his private finances from those of domestic and foreign powers. Never before has a President acted with such disregard for this constitutional prescription.”

The suit could open a new front for Trump as he navigates investigations by special counsel Robert S. Mueller III and congressional committees of possible collusion between his associates and the Russian government during the 2016 presidential campaign.

Democrats plan resolution to demand Trump divest from his business, but chances of passage are slim

If a federal judge allows the case to proceed, Racine and Frosh say, one of the first steps will be to demand through the discovery process copies of Trump’s personal tax returns to gauge the extent of his foreign business dealings. That fight would most likely end up before the Supreme Court, the two said, with Trump’s attorneys having to defend why the returns should remain private.

“This case is, at its core, about the right of Marylanders, residents of the District of Columbia and all Americans to have honest government,” Frosh said. To fully know the extent of Trump’s constitutional violations “we’ll need to see his financial records, his taxes that he has refused to release.”

Racine said he felt obligated to sue Trump in part because the Republican-controlled Congress has not taken the president’s apparent conflicts seriously.

“We’re getting in here to be the check and balance that it appears Congress is unwilling to be,” he said.

The constitutional question D.C. and Maryland will put before a federal judge is whether Trump’s business ownership amount to violations of parts of the Constitution known as the foreign and domestic emoluments clauses.
