Theresa May has recognised in her resignation honours list the MP John Mann, who announced at the weekend he was resigning from Labour.
The former PM selected Mann, 59, for a life peerage in her honours list published on Tuesday.
Mann, who represented Bassetlaw since 2001, revealed on Sunday he was resigning as a Labour MP to devote himself to his role advising the Government on Jew-hate.
He told the Sunday Times: “Corbyn has given the green light to the antisemites and, having done so, has sat there and done nothing to turn that round.”
The Bassetlaw MP who chairs the parliamentary group on antisemitism was made an independent government adviser on antisemitism earlier this year.
Chief Rabbi Ephraim Mirvis congratulated the MP, writing on Facebook: “For more than a decade, he has been one of the world’s foremost campaigners against the scourge of antisemitism.
“British society owes him a debt of immense gratitude for his courageous work and unyielding integrity as a highly principled Member of Parliament.”
In other appointments, May selected for a knighthood Tory Party treasurer Ehud Sheleg, who has donated hundreds of thousands of pounds to Conservative coffers.
The Israeli-born art collector is the director of the Halcyon Gallery on New Bond Street in Mayfair.
