David Cameron is to stand down as MP for Witney, triggering a by-election in the Oxfordshire seat, he has announced.
Mr Cameron told ITV News that he had thought "long and hard" over his choice but had ultimately decided that he would be a "distraction" from the work of government.
David Cameron has told ITV News he has no plans for the future after resigning as an MP.
ITV News Deputy Political Editor Chris Ship tweets:
Cameron said he would stay on as Witney MP after resigning as PM - but he said in practice it was an impossible switch.
The former prime minister has stepped down from his position in parliament as he resigned his seat as the MP for Witney.
He rose to lead the country before an equally dramatic downfall after failing to persuade the public to vote to remain in the EU.
