Political adviser Danny Stone has joined the All Party Parliamentary Group Against Antisemitism as its director.
The group, under the chairmanship of John Mann MP, has been setting the agenda in the UK and abroad in the fight against antisemitism.
The role is a move back into the community for Mr Stone, 28.
A former adviser to Lord Janner, he has spent the past two years as a senior political advisor to the environmental charity Royal Society for the Protection of Birds.
He tells People: “I was missing working in the community. It is nice to be back in Parliament.
“The group has done some really great work and I am looking forward to the next general election and the new wave of MPs coming in. I hope I can continue the trend for trailblazing.”
