A giant blimp of London Mayor Sadiq Khan hovered Saturday above Westminster in a crowdfunded protest against his record on tackling violent crime in the UK capital.

A small crowd of supporters and members of the media gathered to see the giant balloon which depicts the mayor reclining in a small yellow bikini — as it was flown for two hours, the Press Association news agency reported.

Protest organizer Yanny Bruere, who describes himself as a British free speech advocate, said he had set up the crowdfunding campaign in response to London authorities’ decision to allow a “Trump Baby” blimp to be flown during a visit to Britain in July by President Donald Trump.

The blimp’s swimwear is a reference to a controversial weight-loss advertisement banned from the Transport for London network by Khan in 2016 that depicted a woman in a yellow bikini with the slogan “Are you beach body ready?”

Speaking to broadcaster ITV London on Thursday, Khan said: “If people want to spend their Saturday looking at me in a yellow bikini, they’re welcome to do so I don’t really think yellow’s my color though.”
