A giant balloon depictingDonald Trump as an angry, orange baby will fly near Parliament during the US president's visit to the UK next week.
London mayor Sadiq Khan today granted permission for the 20ft (6metre) inflatable, dubbed 'Trump Baby'.
It will fly above Parliament Square Gardens for two hours on the morning of Friday July 13.
The stunt risks raising tensions around the visit as Mr Trump and Mr Khan have clashed repeatedly over terrorism and the Muslim community in London.
Huge protests are expected in London for the first full day of Mr Trump's visit, which will begin next Thursday night when he flies in from the Nato summit in Brussels.
His three day trip is thought likely to include a dinner with business figures at Blenheim Palace, meeting the Queen at Windsor and talks with Theresa May at her country retreat in Chequers. Mr Trump is also thought to be keen to play golf at his courses in Scotland.
The programme is being designed to ensure Mr Trump avoids London and the expected angry protests. He cancelled a trip last year for fear of demonstrations.
The group behind the balloon have raised ￡17,000 through a crowdfunding website to pay for the huge balloon and take it on a 'world tour'.
The group stated: 'If we can troll Donald from the skies wherever he goes for long enough, he'll start seeing "TrumpBaby" in his dreams.'
