Former British Prime Minister David Cameron is standing down as MP for Witney, triggering a byelection in the Oxfordshire seat.
Cameron's decision comes two months after he quit as Prime Minister on July 13 in the wake of defeat in the EU referendum.
Cameron said: "Having fully considered my position over the summer, I have decided that I am going to stand down as the Member of Parliament for Witney.
"There will now be a byelection and I will do everything that I can to help the Conservative candidate win that election.
"In my view, the circumstances of my resignation as Prime Minister and the realities of modern politics make it very difficult to continue on the backbenches without the risk of becoming a diversion to the important decisions that lie ahead for my successor in Downing Street and the Government.
