Published as the party’s annual conference began in Birmingham, it calls for the creation of jails “exclusively for” Muslims who “promote extremism or try to convert non-Islamic prisoners”.

Other ambitions outlined in the so-called “Interim Manifesto” include a ban on mosques receiving money from overseas and the abolition of the “hate crime” category.

Party leader Gerard Batten, who has previously described Islam as a “death cult”, said the policies were intended to “make Ukip a populist party in the real meaning of the word”.

The document claimed segregation in prisons was needed because non-Muslim inmates were frequently forced to convert to Islam “for their own protection from Muslims gangs behind bars”.

Maajid Nawaz, chairman of counter-extremism Quilliam Foundation, described the policy as “the first step to Muslim concentration camps”.

“What next, deportation of all Muslims from these ‘Muslim only jails’? The rest of us, civilised human beings, will resist you to the end,” he tweeted.

Hope Not Hate said the policy demonstrated that “Ukip’s march further and further right continues”.

“Their conference features extreme figures, their manifesto proposes racism and Islamophobia as policies, and their leader spouts vile hate about Muslims,” the anti-racism group added.

Mr Batten has denied he is taking Ukip to the far right, after the party’s former leader Nigel Farage warned it faces “total and utter marginalization” if it moves to the extremes of politics.
