Phillip Lee has defected from the Conservatives to the Liberal Democrats, crossing the floor in the House of Commons as Boris Johnson addressed members of parliament.
The defection of the MP for Bracknell means the government no longer has a working majority.
Lee is the fourth MP to defect to Jo Swinson’s party in the last few months and takes their total to 15.
Speaking in the Commons, Johnson told Lee he wished him “all the best” after watching him sit down with the Lib Dems.
In a statement, the former Tory minister — who supports a second referendum over Brexit — accused Johnson of “feeding division and populism” and of using “political manipulation, bullying and lies.”
“This Conservative government is aggressively pursuing a damaging Brexit in unprincipled ways,” he said.
“It is putting lives and livelihoods at risk unnecessarily and it is wantonly endangering the integrity of the United Kingdom.”
It comes ahead of the showdown vote in the Commons on Tuesday evening when opposition at Tory rebels will attempt to seize control of the parliamentary agenda to block a no-deal Brexit on Oct. 31.
Johnson has dramatically raised the stakes by signalling he will ask for a snap general election if the government is defeated.
