If Donald Trump were to visit the Britain it could give people a "carte blanche" to hold unruly protests, a London assembly member fears.

David Kurten, who represents UKIP, says he is a "big fan" of the controversial US President.

But this week, Mayor of London Sadiq defended people's right to protest as news of his his potential visit later this year broke.

During an annual feast of St George's celebration in Trafalgar Square, Mr Khan said: “We have got a great history in our city of bringing about change by protest, the key thing is for it to be lawful, for it to be peaceful.

“I have no doubt that if he does come, there will be some people who want to express their views loudly and peacefully to the president."

But Mr Kurten believes this gives a "carte blanche" to people wanting to have protests that may not be in a pleasant manner.

He said the UK needs to make the US a best-friend and ally, and ensure his visit is a huge success.

He said: “Some of the things Sadiq Khan says about Donald Trump are quite confrontational, people in London may ignore his qualification about being peaceful.

“He must be really careful with his words because not everybody may take on board that the protests have to be peaceful.”

Last month the Crown Prince of Saudi Arabia, Mohammed bin Salman visited the UK as part of a state visit and met both Prime Minister Theresa May and members of the royal family.

Yet Mr Kurten criticised the way the Saudi Prince’s visit was handled.

He said: “There is a war going on between Saudi Arabia and Yemen. We think that British bombs are being used by Saudi Arabia in Yemen and children are dying.

“This is far worse than any allegations that anyone has made against Donald Trump and yet Sadiq Khan said nothing about the state visit by the Crown Prince of Saudi Arabia.”

Mr Kurten added: “The mayor didn’t encourage any protests against the Saudi Arabian Royal family so why is he so keen to protest against Donald Trump.

"That seems to me to be hypocrisy.”
