LONDON - 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.
- Sunak attack -
The announcement came just hours after Johnson controversially rewarded his closest Brexit allies -- and officials implicated in the "Partygate" saga -- in his prime ministerial resignation honours list.
At the same time, his former culture secretary Nadine Dorries announced that she was quitting as an MP with immediate effect.
Johnson led the Tories to a thumping 80-seat majority in the December 2019 general election on a promise to "get Brexit done", allowing him to railroad through parliament his divorce deal with the European Union.
But he was undone by his handling of the Covid pandemic, "Partygate" and a succession of other scandals that led to a ministerial rebellion in July last year.
He quit as prime minister and left office in September last year, although rumours persisted that he wanted another shot at the top job.
Rishi Sunak, who was one of Johnson's top team who quit, has been trying to steady the ship since becoming prime minister in October last year.
But Johnson's resignation will likely be seen as his revenge, with Sunak and the Tories well down in the polls to the main opposition Labour party -- and a general election looming next year.
"When I left office last year the government was only a handful of points behind in the polls. That gap has now massively widened," said Johnson in his letter.
"Just a few years after winning the biggest majority in almost half a century, that majority is now clearly at risk.
"Our party needs urgently to recapture its sense of momentum and its belief in what this country can do."
He added: "The Conservative Party has the time to recover its mojo and its ambition and to win the next election."
Johnson, who was sacked from his first job at The Times newspaper for making up a quote, made his name as Brussels correspondent of the Daily Telegraph peddling euromyths.
He first became an MP in 2001 until 2008, then quit to serve two four-year terms as London's mayor. He became an MP again in 2015, going on to be foreign secretary under Theresa May.
