Donald Trump has been faced with giant projections of 'USS John McCain' and Barack Obama approval ratings projected onto London landmarks during his visit.

Approval ratings showing the president as having a score of 21 per cent in the UK, compared with his predecessor's 72 per cent, were projected onto the Tower of London.

An image of a USS John McCain cap was also projected onto Madame Tussauds and tweeted to America's leader by an anti-Brexit campaign group.

The group, named Led By Donkeys, said: "We read the story about the sailors on a US warship being ordered to hide from you because you’re triggered by the name on their hats.

"So we turned Madame Tussaud's into a giant USS John McCain baseball cap. Welcome to London!"

They continued to tweet the former reality TV star saying: "Just so you know, you’re wildly unpopular here in Britain. Sad! People really don’t like you (though they love @BarackObama). Hope you like seeing your failing approval numbers projected onto the Tower of London."

To coincide with the start of Trump's three-day UK state visit, protest banners were also hung from London's Vauxhall Bridge and a teenager mowed a gigantic penis in the grass of the lawn outside London Stansted airport with accompanying words that read "Oi Trump".

It is just the beginning of the British protests against Trump, with up to 250,000 demonstrators expected to take to the streets in London tomorrow, as well as protests being planned in other big cities including Manchester, Belfast and Birmingham.

The rally will march from Trafalgar Square down Whitehall to Parliament Square while the president holds talks with British Prime Minister Theresa May in Downing Street.

The leader of the opposition party Jeremy Corbyn will join the protest, with the 70-year-old expected to speak in central London tomorrow.

According to a recent poll by YouGov and Queen Mary University of London, over half of Londoners (54 per cent) said they oppose Mr Trump’s visit, with just more than 24 per cent supporting it.

On Twitter today, the US president insisted his visit to the UK was going "really well," writing: "The Queen and the entire Royal family have been fantastic. The relationship with the United Kingdom is very strong. Tremendous crowds of well wishers and people that love our Country.

"Haven’t seen any protests yet, but I’m sure the Fake News will be working hard to find them. Great love all around. Also, big Trade Deal is possible once U.K. gets rid of the shackles. Already starting to talk! [sic]."
