Sadiq Khan savages Donald Trump for ‘playing into the hands’ of IS

London mayor Sadiq Khan on Thursday criticised Republican presidential candidate Donald Trump's proposals on Muslims and immigration.

Khan, who is of Pakistani descent and became the first Muslim mayor of a major Western capital when he was elected in May, arrived in Chicago to begin a US trip promoting trade ties.

Trump at one point called for a ban on Muslim immigration into the US. The candidate has since modified his stance to urge an immigration ban from countries with "a proven history of terrorism" and for "extreme vetting" of immigrants. 

"We play straight into the hands of those who seek to divide us, of extremists and terrorists around the world, when we imply that it's not possible to hold Western values dear and to be a Muslim," Khan said to applause from an audience at The Chicago Council on Global Affairs. It was his first visit to the US as London's mayor.
