Lord Sacks, the former chief rabbi, said he was “honoured” to be one of two members to introduce former Labour MP John Mann to the House of Lords, as he takes on a role as an independent advisor to the Government on antisemitism.

The former Labour MP was officially appointed to the upper house in a ceremony on Tuesday afternoon flanked by Lord Sacks and Lord Clarke of Hampstead.

The peer is now tasked with providing independent advice to ministers on how to tackle anti-Jewish prejudice.

Ahead of Tuesday’s ceremony, the former Chief Rabbi tweeted: “It will be an honour to be one of the members to introduce Lord Mann into the House of Lords later today. Thank you for all you have done and all you will continue to do on behalf of us all.”

Lord Mann had resigned as an MP on Monday after being appointed as Steward and Bailiff of the Three Hundreds of Chiltern – in the archaic process that effectively resigned him from the Commons.

As MP for Bassetlaw, he had chaired the all-party parliamentary group on antisemitism, having first been elected as an MP in 2001.
