Laurence Fox is being sued by Ru Paul’s Drag Race star Crystal, a LGBTQ+ charity boss and Coronation Street actress Nicola Thorp for calling them “paedophiles” on Twitter.
The London mayoral candidate, running on a platform of free speech, now faces High Court proceedings after the online outbursts in October 2020.
Fox accused Sainsbury’s of "promoting racial segregation and discrimination" after the retailer promoted its plan to recognise Black History Month.
The actor said creating "safe spaces" for black workers amounted to "segregation".
Fox faced a backlash from hundreds of Twitter users, and Crystal responded tweeting: "Imagine being this proud of being a racist. Total snowflake behaviour."
The former Lewis actor shared her comment, saying: "Says the paedophile."
Stonewall’s Simon Blake responded to Mr Fox saying: "What a mess. What a racist t***." Mr Blake
The actor then hit back at a number of people "falsely accusing him of racism" by calling them "paedophiles".
Fox’s tweets were later deleted, but Crystal released a statement on Monday saying she had instructed lawyers to pursue legal action against him.
In a statement shared on Twitter on Fox said: "If the game nowadays is to throw baseless insults and accusations about, then we should all be free to participate.
"Having said that, I have deleted the tweets posted yesterday, in response to being repeatedly, continuously and falsely smeared as a racist, as they just serve as a distraction to the important work that needs to be done."
The trio have instructed law firm Patron Law on their defamation lawsuit. Crystal and Mr Blake initially threatened legal proceedings last year, but officially filed the claim in the High Court on April 1.
Ms Thorp is also named as a claimant, along with Mr Blake and Crystal.
When asked about the defamation case at a launch for his campaign today, Mr Fox said: “I must check my emails, I’m not aware of that.”
He added: “People can call me whatever they want.”
When told it was he who had allegedly called the three claimants paedophiles, he replied: “I was called a racist.”
Mr Fox doubled down, saying: “Free speech. You throw meaningless and baseless insults at someone you get a meaningless and baseless insult in return.”
Lewis actor Mr Fox, the Reclaim Party candidate for mayor, is campaigning to ease lockdown,which he claims is a “tyranny”, and against political correctness.
“Londoners need to be free to get back to work, back to having fun, back to seeing our friends and families,” he said. “The heart of our city is being hollowed out while we stay away.
“Lockdown has cost London’s economy more than £55 billion, but it has cost Londoners far more in lost income, missed opportunity, time without loved ones, cancelled operations and rising crime.”
