When he was elected Speaker back in 2009, John Bercow pledged to serve for nine years but he has now revealed he wants to retain the role until the end of the next parliament in 2022.
Mr Bercow, who is campaigning to be re-elected as MP for Buckinghamshire, told Sky News that the abrupt end to the last parliament and Britain’s decision to leave the EU caused him to change his mind.

He is a self-serving parasite of the worst order
He said: "I had originally indicated an intention to serve for approximately nine years. If I may legitimately say so, I made that commitment eight years ago, it was before the Fixed Term Parliament Act, it was before the EU referendum."
He used Theresa May’s decision to call a snap election despite previously ruling it out to justify changing his planned departure date.
The 54-year-old continued: "We're in a very different situation… the Prime Minister very properly is entitled to change her view about whether the national interest would be served by an earlier election rather than a later one.
