Washington, May 16: Donald Trump, the presumptive Republican presidential candidate has warned that he may not share a good relationship with UK if he becomes the president.
Reacting on Donald Trump's idea of putting a temporary ban Muslim's entry to US, Sadiq Khan said that Trump's views on religion will make the world less safe if he becomes President.
"I was offended by Mr Khan's ignorant remark", said Donald Trump in an interview.
He even challenged Sadiq Khan to an IQ test.
"He doesn't know me, hasn't met me, doesn't know what I'm on about," said Trump.
"I think they're very rude statements and frankly tell him I will remember those statements. They're very nasty statements," added Trump.
Sadiq Khan on Tuesday (May 10) hit out at Donald Trump for signalling that he would exempt him from his proposed temporary ban on Muslims entering the US, saying his "ignorant" comments play "into the hands of extremists".
Trump's ignorant view of Islam could make both our countries less safe - it risks alienating mainstream Muslims around the world and plays into the hands of the extremists," added Khan.
Trump called for a "total and complete shutdown" of the country's borders to Muslims in the wake of the San Bernardino terrorist attack in December 2015.
