Sadiq Khan has warned Donald Trump that there will be 'no red carpet' should he visit the United Kingdom.

The Mayor of London renewed his war of words with the U.S. President ahead of a proposed state visit to the capital.

Theresa May had officially invited Trump to the UK in January but the trip was left out of the Queen's Speech last month, ending hopes it would happen this year.

Despite an invite from the UK government, both sides have failed to arrange a date amid reports that Mr Trump has been put off by the threat of large-scale protests.

Among the President's main opponents in the UK has been Mr Khan, who opposed Trump's travel ban which targeted people from mainly Muslim countries.

Speaking to CNN about the mooted state visit, Mr Khan said he was 'ready to play my role' when it came to challenging people's opinions.

He added: 'State visits are different from a normal visit and at a time when the President of the USA has policies that many in our country disagree with, I am not sure it is appropriate for our government to roll out the red carpet.

'If you somehow think it is not possible to be a Muslim and a proud westerner I am happy to disabuse you of that idea, whether you are a reporter for CNN or Donald Trump.'
