London CNN  — 

UK Prime Minister Boris Johnson has survived a confidence vote by members of his own party – but the final count of lawmakers who rebelled against him was far higher than his supporters expected.

After a tidal wave of recent criticism – which included illegal, lockdown-breaking parties thrown in his Downing Street offices – Johnson squeaked by with 211 votes to 148 in a secret ballot on Monday.

The government hailed the result, with Johnson saying he thought “this is a very good result for politics and for the country.”

“I think it’s a convincing result, a decisive result, and what it means is that as a government we can move on and focus on the stuff that really matters to people,” Johnson said.

Yet his thin margin of victory means that 41% of his own parliamentary party refused to back Johnson, three years after he led the Conservative Party to a landslide victory in the last general election.

Voting began at 6 p.m. (1 p.m. ET) Monday after Johnson urged Conservative lawmakers to back him and reminded them that he had led the party to its biggest electoral win in 40 years, according to a letter he wrote seen by PA Media.

The large rebellion by his lawmakers will leave Johnson’s reputation diminished and could damage his ability to push through legislation. Disappointing results for the party in upcoming polls could also heap more pressure on Johnson, as Conservatives face two difficult parliamentary by-elections in late June.

Despite the victory, the opposition Labour Party has said that by hanging onto power this time, Johnson makes the prospect of an early election even more likely. Labour Party leader Keir Starmer predicted to LBC that Monday’s vote would mark “the beginning of the end” of the Prime Minister’s political career – no matter which way the vote went.

“If you look at the previous examples of no confidence votes, even when Conservative Prime Ministers survive those … the damage is already done,” the opposition leader told LBC Monday. “Usually, they fall reasonably swiftly afterwards.”
