David Cameron to quit as Conservative MP for Witney

Former Prime Minister David Cameron is standing down as an MP, triggering a by-election in his Witney seat.

Mr Cameron, who quit as Prime Minister shortly after the EU referendum, said he had "thought about (his future as an MP) long and hard over the summer", deciding it was now "the right thing to do to stand down" from his constituency in Oxfordshire.

He added: "In my view, in modern politics, with the circumstances of my resignation, it isn't really possible to be a proper backbench MP as a former Prime Minister.

"I think everything you do will become a big distraction and a big diversion from what the Government needs to do for our country."
