Yesterday, a small crowd of supporters and amused onlookers gathered in Parliament Square to watch the launch of "Bikini Khan."
The choice of the bikini was a reference to Khan's 2016 removal of advertisements featuring a woman in a bikini from the subway and the transit system for promoting "unhealthy or unrealistic" body images.
At the launch of the Khan blimp, organisers wore T-shirts that read "Make London Safe Again," a reference to London's crime rates under Khan's watch and Trump's "Make America Great Again" slogan. Some wore Khan face masks. One woman had an inflatable pig with a Khan mask on.
When the balloon launched, a handful of people shouted, "Higher, higher."
Bruere has come under scrutiny over a deleted Twitter account. Bellingcat, a group of online investigators, said it found deleted tweets by him that some have said were anti-Semitic and promoted conspiracy theories.
Bruere told Sky News that the old tweets are being taken out of context. "This Twitter account was deleted over eight months ago. These tweets were taken out of context. They were part of a wider thread," he said.
He later added, "I'm called far-right for doing this. However, when the Trump team did it, they were widely applauded."
Organisers of both balloon efforts said they were overwhelmed by the response and plan to take the blimps on tour. The organisers of the Bikini Khan balloon raised more than £59,000 through crowdfunding. The Trump Baby balloon crowdfunding effort raised more than £34,000.
Trump suggested that the Trump Baby balloon was one of the reasons he spent little time in London during his visit.
"I guess when they put out blimps to make me feel unwelcome, no reason for me to go to London," Trump told the Sun newspaper in July.
Khan appeared laid-back, even amused, about the whole thing. "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 colour, though," he said.
