Mann confronts Livingstone over anti-Semitic claims
Labour MP John Mann has verbally attacked Ken Livingstone as tensions rise over anti-Semitic claims.
The former mayor was heading for the BBC Westminster studio when he was confronted by his critic.
Mr Livingstone, who faces calls for his own resignation for defending Naz Shah, said: "He went completely over the top."
And he told Daily Politics presenter Andrew Neil that previously Mr Mann was "screaming I was a bigot down the phone".
