Respect MP George Galloway has been taken to hospital with a suspected broken jaw after he was attacked in the street, his spokesman said.
Mr Galloway, who also suffered a suspected broken rib and severe bruising to his face and head, was posing for pictures with people in Golborne Road, Notting Hill, west London, last night, when a man shouted a comment about the Holocaust and attacked him, according to the spokesman.
Police were quickly on the scene and made an arrest.
Mr Galloway was taken to St Mary’s Hospital, Paddington, where he is expected to remain overnight.
His spokesman said: “George was posing for pictures with people and this guy just attacked him, leapt on him and started punching him.
“It appears to be connected with his comments about Israel because the guy was shouting about the Holocaust.”
The spokesman did not know whether the attacker was an Israeli, an EDL-supporter or had some other motivation for attacking the Bradford West MP.
Mr Galloway was interviewed earlier this month by West Yorkshire Police following a speech in Leeds in which he claimed Bradford was an Israeli-free area.
The spokesman said Mr Galloway had described himself as being “in a pretty bad shape “.
A Metropolitan Police spokesman said: “Police were called at approximately 1940 hours to Golborne Road, W10, after a man was assaulted in the street.
“Officers attended. The suspect was found a short time later and stopped.
“He was arrested on suspicion of ABH (actual bodily harm) and taken to the south London police station where he remains.”
In 2008 Mr Galloway was pelted with a rubber stress ball as he was campaigning in an open-top bus in London.
The firebrand politician received medical treatment but was not taken to hospital.
A man was arrested and cautioned over that incident.
