John McDonnell has apologised for the way the Labour Party initially handled anti-Semitism claims.
The comments come after Jeremy Corbyn declined to apologise after in a BBC interview with Andrew Neil.
The Labour leader was asked four times whether he would like to apologise after Chief Rabbi Ephraim Mirvis claimed “a new poison – sanctioned from the very top – has taken root” in Labour.
Mr Corbyn said his government will protect “every community against the abuse they receive”.
