Corbyn, 73, was among 17 people who were arrested for breaching Health Protection Regulations at the demonstration at Speaker’s Corner, in Hyde Park, on January 2.
A crowd of between 200 and 300 people gathered to protest against lockdown restrictions and their civil liberties being curtailed.
It came after Corbyn was fined and arrested on New Year’s Day after leading a New Year’s Eve anti-lockdown protest near the London Eye, in the centre of the capital.
Corbyn, brother of the former Labour leader Jeremy Corbyn, posted a video of what was dubbed the ‘NYE Party of Parties’ on his Twitter feed, proclaiming: ‘TOTAL SUCCESS! #NYEPartyofParties by London Eye.
‘Over 1000 defied all threats +chanted #LetLondonLive! & #Corbyn4London after I announced I will stand for Mayor! Thank you +well done all!’
The conspiracy theorist has now been arrested at least five times since the start of the coronavirus pandemic and has received fines totalling more than £10,000.
