A protester, wielding the Ukrainian flag, was kicked out of a Stop The War rally in London.
The man can be seen waving the flag and yelling "shame on you" to the former Labour leader.
The meeting has been subject of media interest, as former Labour shadow chancellor John McDonnell and Labour grandee Diane Abbott were expected to attend the event.
Protester is ejected from the meeting heckling Jeremy Corbyn and wielding a Ukraine flag.

However Labour leader Sir Keir Starmer is reported to a have threatened removal of the Labour whip to any MP from his party speaking at the event and that is critical of Nato and the West.
LabourList reported that the senior Labour MPs are not attending the event.
Mr Corbyn told the rally: "If there’s one heartening thing at the moment, it has been the scenes of thousands of people on the streets of Russia standing up to their government against the war."
This comes after eleven Labour MPs that signed an open letter from the Stop The War Coalition which criticised Nato withdrew their names.
The eleven were threatened with the removal of the whip if their names were not taken off the letter.
A Labour spokesperson said: "The small number of Labour MPs that signed the Stop The War statement have all now withdrawn their names.
"This shows Labour is under new management.
"With Keir Starmer’s leadership there will never be any confusion about whose side Labour is on – Britain, Nato, freedom and democracy – and every Labour MP now understands that."
