It's big, it's orange, and it's wearing a diaper. And now the blimp depicting President Trump as an infant with an iPhone in hand has permission from the mayor of London to fly over Parliament Square Garden when the U.S. leader visits London next week.

On Thursday, a spokesman for Mayor Sadiq Khan confirmed to The Washington Post that his office had granted permission for the blimp to take off, saying in an email that Khan “supports the right to peaceful protest and understands that this can take many different forms.”

The spokesman added that the activists flying the blimp “will also need to receive the necessary approvals from the Metropolitan Police and National Air Traffic Service in order for it to fly.”

Trump is scheduled to visit London next week after much delay, with concerns over protests having scuttled previous plans. He has repeatedly angered Londoners with comments about their city, including remarks at a National Rifle Association meeting in May in which he claimed that London has strict gun laws but has such a bad knife problem that a hospital in the city looks like a “military war-zone hospital.”

“Yes, that’s right, they don’t have guns,” he said. “They have knives, and instead there’s blood all over the floors of this hospital.”

The activists who planned the blimp stunt, known as “Trump Baby,” raised more than $20,000 through an online crowdfunding campaign. About 10,000 people also signed a petition asking for permission to fly the massive balloon. The campaign asked donors to “make our six meter high orange, inflatable baby with a malevolent face and tiny hands fly over central London during Trump's U.K. visit."

After Trump's visit was announced in April, British Foreign Secretary Boris Johnson tweeted that he is looking forward “to seeing our closest ally and friend on the GREATest visit ever.”

Now it looks likely that the visit will include an appearance by the blimp, which activists hope will take to the skies for two hours on July 13, coinciding with a “Stop Trump” march planned for the same time. The creators of the blimp did not immediately respond to requests for comment.
