When the artist wrote on Facebook that the mural was to be removed, Mr Corbyn responded with a message from his personal Facebook account.
He wrote: “Why? You are in good company. Rockerfeller destroyed Diego Viera’s mural because it includes a picture of Lenin.”
Mr Corbyn did not respond to request from the JC to explain his comments when they became public in 2015.
Today, a spokesperson for the Labour leader said: "In 2012, Jeremy was responding to concerns about the removal of public art on grounds of freedom of speech.
“However, the mural was offensive, used antisemitic imagery, which has no place in our society, and it is right that it was removed."
Mr Ockerman’s Freedom for Humanity was criticised by Lutfur Rahman, the controversial Tower Hamlets mayor at the time.
He said he was concerned the work could be interpreted as offensive to Jews because “the images of the bankers perpetuate antisemitic propaganda about conspiratorial Jewish domination of financial and political institutions”.
