Prime Minister Theresa May has appointed Bassetlaw Labour MP John Mann as an independent adviser on anti-Semitism.
The role will see Mr Mann, who is chairman of the All Party Parliamentary Group on anti-Semitism, provide independent advice on how to tackle the issue, Downing Street said.
Theresa May says Mr Mann is a 'key voice on this matter.'
John Mann MP said:
Labour has been rocked in recent years with claims by some of its MPs that the leadership is not tackling anti-Semitism.
The Conservative Party has also been accused by some of not dealing with allegations of Islamophobia within the party in a robust enough way.
Mr Mann has been a critic of the way Labour leader Jeremy Corbyn has dealt with anti-Semitism allegations in the party. His appointment by the PM comes at a sensitive time for the Labour leader as Mr Corbyn is presenting an initiative to the party's governing National Executive Committee on Tuesday aimed at speeding up the process dealing with allegations of anti-Semitism. However, some MPs have said that Mr Corbyn's plan does not go far enough.
