The Liberal Democrat Party will tonight announce its parliamentary candidate for Hampstead and Kilburn.

Among the party’s shortlist of five hopefuls is former Muslim extremist and author Maajid Nawaz, who set-up Quilliam – the world’s first counter-extremism think-tank. He was recruited into the hardline global Islamist organisation Hizb ut-Tahrir as a teenager and spent time in an Egyptian jail as a political prisoner before becoming a democracy campaigner.

Last year, he published a memoir entitled Radical, which recounts his journey from religious extremist to publicly renouncing Islamist ideology.

Other Lib Dem candidates shortlisted include former Kilburn councillor and Camden Council cabinet member James King, retired GP Catherine Royce and David Bouchier, who has stood for Hampstead in Camden Council elections twice before.

Disability campaigner David Buxton, who is thought to have been the only deaf councillor to use interpreters when he was serving on councils in Southwark and Epsom, is also on the list.

Members will vote at Hampstead Synagogue’s community hall, West Hampstead, tonight.
