Ex-British prime minister Boris Johnson resigns as MP

Britain's former prime minister Boris Johnson on Friday said he was quitting as a member of parliament, claiming he had been forced out in a stitch-up by his political opponents.

The 58-year-old populist politician has been under investigation by a cross-party committee about whether he repeatedly lied to parliament over COVID lockdown-breaking parties when he was in office.

In evidence earlier this year he angrily insisted he had not.

But as the committee prepares to make public its findings, he said they had contacted him "making it clear... they are determined to use the proceedings against me to drive me out of parliament".

The Privileges Committee, which has a majority of MPs from his own Conservative party, has powers to impose sanctions for misleading parliament, including suspension.

Ordinarily, suspension of more than 10 working days leads to a by-election in the MP's constituency.

Johnson, though, pre-empted any finding -- or having to fight to remain an MP in his Uxbridge and South Ruislip constituency in northwest London where he holds a slim majority of just over 7,000 -- by quitting.

He denounced the committee, chaired by veteran opposition Labour MP Harriet Harman, as a "kangaroo court".

"It is very sad to be leaving Parliament - at least for now -- but above all I am bewildered and appalled that I can be forced out, anti-democratically... with such egregious bias," he said.
