President Donald Trump has disputed the size and reason for the gathering of thousands of people demonstrating over his visit to the U.K.

On Tuesday, protesters marched from Trafalgar Square to Parliament Square in the British capital in opposition to Trump's three-day state visit, describing themselves as members of the "Carnival of Resistance."

Many carried placards protesting Trump's policies on minorities, healthcare, climate change and Palestinians. The signs carried messages such as, "Dump Trump" and "Trump not welcome," while a blimp depicting Trump as a giant baby with tiny hands floated outside Parliament as the president passed.

While the exact numbers were hard to verify, organizers of the London rally say at least 75,000 people turned up to voice their disapproval, Channel 4 News reported.

London's Metropolitan police said that thousands had turned up, while the BBC reported that the protester numbers were in the thousands but far short of the estimated 250,000 that turned up last July to oppose Trump's working visit to the U.K.

A spokesperson for Trump Baby U.K., the group behind the giant presidential blimp, told Newsweek the turnout was in the "tens of thousands" adding that it was a "great turn out when you consider the fact it's a working day and (there was) appalling weather."

The Met police said that they had deployed more than 3,000 officers but had only made one arrest.

Demonstrators were prevented from marching past Downing Street where Trump was meeting the British Prime Minister Theresa May and it appeared that Trump may have mistaken the jeers for cheers.

In a joint press conference with May, Trump dismissed claims that there was antipathy against him, describing how at the demonstration there had "tremendous spirit and love."

"There was great love, there was an alliance and I didn't see the protesters until just a little while ago and it was a very, very small group of people put in for political reasons, so it was fake news," he said.

Trump doubled down on his assessment of his reception, tweeting on Wednesday: "I kept hearing that there would be 'massive' rallies against me in the UK, but it was quite the opposite.

"The big crowds, which the Corrupt Media hates to show, were those that gathered in support of the USA and me. They were big & enthusiastic as opposed to the organized flops!"

Trump was right in saying there were people among the demonstrators supporting his visit. There were a handful of Trump supporters who braved the crowds. George Clinton, from Richmond, Virginia, carried a U.S. flag to show his support for the visit.

He told Channel 4 News: "Queen Elizabeth should declare a snowflake emergency, there are a lot of people who are down on the United States and that's very sad."

A Trump Baby spokesperson attributed the attack to the "far right" and that the actual Trump Baby would be going to Dublin "to troll Trump on his next destination."

In Northern Ireland several dozen protesters from trade unions and advocacy groups gathered at Belfast's City Hall to express their opposition to Trump's arrival on Wednesday.

However, there was a small group of pro-Trump supporters waving the stars and stripes and Make America Great Again flags, who got into a verbal spat with the demonstrators, The Belfast Telegraph reported.
