Anti-vaxxers have triggered a security response and chaos outside Parliament - and blocked Boris Johnson's route to the Commons.
Tory MP Bob Blackman's car was swarmed by activists, who were blocking the road in Parliament square.
They pounded on the vehicle's bonnet and windscreen, accusing him of hitting Piers Corbyn, a leading Antivaxxer and brother of Jeremy Corbyn, with his car.
Mr Blackman was stuck in the crowd of people, just outside Parliament's gates, for around 20 minutes until Police defused the situation. Meanwhile, officers lined up on the inside of the gates.
The prime minister was due to appear in the Commons at 3.30pm and then at 4.30pm, but did not actually begin his statement until just after 5pm.
Video posted online show how Mr Corbyn, a famous face in protests against vaccines and coronavirus restrictions, banged on a blue car with a microphone and then his hand.
Some protesters held signs reading "I'll move on when he moves out" - the the day the PM was to face his first PMQs since being fined for breaking lockdown rules.
Johnson will face a major vote by MPs this Thursday on whether to formally investigate him for 'misleading Parliament'.
The Commons will decide whether to commence a probe over claims he deliberately misled MPs by saying “all guidance was followed completely” in No10.
Speaker Lindsay Hoyle confirmed the move today after talks with Opposition MPs including Labour leader Keir Starmer.
MPs will hold a vote on whether to refer the matter to the Privileges Committee, while Boris Johnson is trying to move on from Partygate on a visit to India.
If approved the committee could investigate and find Boris Johnson in contempt of parliament - like War Secretary John Profumo after he lied about an affair in 1963.
If found guilty he could even be suspended from the Commons.
However the committee could not start a probe unless MPs vote for it, and the PM still has an 80-odd seat majority - suggesting the vote will not pass.
