London (CNN) A giant blimp of London Mayor Sadiq Khan will be seen in the UK capital's skies this weekend after protesters were given permission to fly the crowdfunded balloon in Westminster.

More than 3,000 supporters have donated more than £58,000 ($75,500) in total to fund the 29-foot balloon, which depicts the mayor reclining in a small yellow bikini.

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 last month's visit to Britain by US President Donald Trump.

He said the Parliament Square event on Saturday morning "marks the fightback for free speech in our country."

Bruere, who has set up a "Make London Safe Again" group on Facebook, accuses Khan of doing too little to prevent violent crime in London.
