Which MPs are standing down at the election?
The general election date is set and most MPs are entering campaign mode. Others, however, are clearing out their desk for the last time.
The House of Commons will lose over 1,000 years of parliamentary experience with more than 70 incumbents preparing to stand down - and there may be more to come.
Here are the ones we know about so far:
Ken Clarke is the longest serving MP in the House of Commons, known as the father of the house, having served his Rushcliffe constituency for almost half a century.
A long-time supporter of the UK's membership of the EU, he was expelled from the Conservative Party by Boris Johnson, after he rebelled against the government over Brexit.

"With great sadness" former Chancellor and Foreign Secretary Philip Hammond (Runnymede & Weybridge) said he would leave the House of Commons after not being restored to the Conservative Party before the election.

The only person who was actually elected as an independent in 2017 Sylvia Hermon (North Down).
Nicky Morgan (Loughborough), the current culture secretary, surprised Westminster watchers by announcing her departure, citing the "clear impact" on her family and "the other sacrifices involved in and the abuse for doing the job of a modern MP".
