Hollande's Warning To Britain Over Leaving EU

French President Francois Hollande has warned there will be "consequences" if Britain votes to leave the EU.

Mr Hollande made the comment during a joint news conference with David Cameron at the end of a one-day Anglo-French summit in Amiens, northern France.

The summit has been overshadowed by French finance minister Emmanuel Macron's warning that the Calais 'Jungle' - home to thousands of migrants wanting to get to the UK - could be moved to Kent if Britain leaves the EU.

Mr Hollande did not repeat this warning, but left no doubt that he wants Britain to vote to stay in the EU in the June 23 referendum.

"I hope the UK remains in Europe," the French President said.

"It is in the interest of the UK, it is in the interest of Europe, but the people are always sovereign."

He added: "There will be consequences if the United Kingdom leaves the European Union.

"There will consequences in lots of fields: the common market, on the financial centres, there will be consequences for the economic development between our countries.

"I'm not suggesting that it's all going to collapse, I don't want to be catastrophic, but there will be consequences."

During the news conference, Mr Cameron announced a £17m UK investment in enhanced security in Calais.

Part of the money will also be used to help relocate migrants at the 'Jungle' to other parts of France or their home countries.

"The United Kingdom has not faced anywhere near the scale of migrants coming to Europe as other countries, because we are outside Schengen and we retain control of our borders, and in Calais we have worked together with the French to strengthen security to deter migrants from trying to enter Britain," the Prime Minister said.

Mr Cameron also announced a series of ways in which Britain and France plan to work more closely together on security issues and to fight terrorism.

Earlier, Germany's finance minister Wolfgang Schaeuble told a conference of the British Chambers of Commerce in London that Europe would be "less stable and more volatile" without Britain in the EU.

Asked what Germany would do if Britain left the EU, Mr Schaeuble said: "We would cry. But I hope we will not."
