The saga between Donald Trump and Sadiq Khan continues.
The newly-elected Mayor of London has now said that he would welcome the presumptive Republican presidential nominee to London to "educate" him on Islam and its compatibility with Western values.
Speaking to NBC, Khan again said Trump's views on Islam were "ignorant" and that he's "inadvertently playing into the hands of extremists".
"To suggest that it's incompatible to be Western and to be Muslim is, I think, really, really risky," he said.
"I want Donald Trump to come to London so I can introduce myself to him as a mainstream Muslim, very, very comfortable with Western liberal values, but also introduce him to hundreds of thousands, dare I say millions of Muslims in this country, who love being British, love being Western.
"I want to educate Donald Trump. I want to show him that you can be Muslim and be Western."
The cold-war-of-words between the two started when Khan expressed concern that if Trump became president then he would not be able to enter the US due to his faith, but dates back to Trump's statement last year that there should be a ban on all Muslims entering the country.
That statement from Khan ushered Trump to say that Khan could be an "exception" to the rule, an offer Khan declined.
Seemingly backed into a corner, the billionaire property magnate then said the ban was "just a suggestion".
The question now is: Will Trump concede anymore ground?
