UKIP is expected to include a ban on full-face veils, worn by some Muslim women, in their official general election manifesto. Paul Nuttall, the party’s leader, is due to launch an ‘integration agenda’ on Monday.

Speaking on BBC’s Andrew Marr show, Mr Nuttall said wearing the burka and niqab in public acts a barrier to social harmony as well as being a security risk. Women who defied the ban would be fined, he added. The agenda will also reportedly call for the outlawing of Sharia law and all existing sharia courts to be shut down.

Mr Nuttall told the programme: ‘We have a heightened security risk at the moment and for CCTV to be effective you need to see people’s faces. Secondly, there’s the issue of integration. I don’t believe you can integrate fully and enjoy the fruits of British society if you can’t see people’s faces.’
