US President Donald Trump says he has decided not to meet Jeremy Corbyn on his trip to Britain, describing the Labour Party leader a "negative force.”

Speaking at a news conference on Tuesday during his state visit to London, Trump claimed that he had been approached by Corbyn, who boycotted Monday�s banquet held in his honor, for a meeting.

"I don�t know Jeremy Corbyn, never met him, never spoke to him. He wanted to meet today or tomorrow and I decided that I would not do that," Trump told

"I think that he is, from where I come from, somewhat of a negative force. I think that people should look to do things correctly as opposed to criticize. I really don�t like critics as much as I like and respect people that get things done,” he added.

Earlier in the day speaking at a protest rally in Westminster, Corbyn said he was "very disappointed" by Trump�s attack on the London Mayor Sadiq Khan, whom the US leader accused of being a "stone cold loser" and “nasty.”

The opposition Labour leader did not mention Trump by name but he did refer to "our visitors,” and said all governments must oppose racism and misogyny.

"So I say to our visitors that have arrived this week. Think on please about a world that is one of peace and disarmament, is one of recognizing the values of all people, is a world that defeats racism, defeats misogyny, defeats the religious hatred that have been fuelled by the far-rights in politics in Britain, in Europe and the United States."

Corbyn told protesters he was prepared to have "a dialogue" with anybody about building a more peaceful, just world.

Meanwhile, London Mayor Sadiq Khan called for a tougher government position against Trump and his “playground” behavior.

“I’m hoping that Theresa May stands up for our country and does say boo to a goose,” Khan said on Tuesday.

London Mayor Sadiq Khan urges UK PM May to stand up to Trump and his childish behavior.

Khan criticized the US president for his divisive policies and said that Trump was acting like children and there was a need for the British government to challenge his ideas on women and minorities.
