A six-meter, novelty-sized Donald Trump will be found floating above London if a group of British protesters successfully have their way.

An online petition to get a huge Donald Trump blimp to fly over London during the US president's visit to the UK on July 13 has almost 6,000 signatures already. 

Dubbed Project Trump Baby, the founders – activist Leo Murray and his friends – have already raised over 7,000 pounds (9,300 US dollars) by crowdfunding to get the 6m high "orange baby" Trump made by a professional inflatables company. 

In addition to the floating giant "Trump Baby" flying above the UK Parliament, the protest group has a further plan to distribute 1,000 mini "Trump Baby" balloons around London also on July 13.

"So when Trump visits the UK on Friday July 13 this year, we want to make sure he knows that all of Britain is looking down on him and laughing at him,” Murray has also written an editorial in The Guardian, explaining the launch could be a day of "national pride and unity" for Britain.

"As Trump Baby swells and begins to ascend to the sky above Westminster, our spirits would be lifted," Murray wrote. “If launched, Trump Baby will spread cheer and goodwill and put smiles on millions of people around the globe as we remember our common humanity.”

However, the group said: "Unfortunately, we need the Mayor of London's permission to be able to fly Trump Baby from Parliament Square – and Sadiq's team at City Hall have told us that flying Trump Baby does not qualify as a 'protest'."

The Mayor's office gave a reason for the ban, insisting that "the only form of protest that is legally allowable on their land is ‘a gathering of people, with banners and placards.’ We are fairly sure this doesn't make any sense, but their key objection is that flying a large inflatable will occupy a corner of the square which will then not be available for gatherings of people with banners and placards – thereby depriving them of freedom of speech,” Murray wrote.
