The Family Law Café in London said it had suspended Joanna Toch “with immediate effect pending an internal review into her recent comments on Twitter”.

Ms Toch, who founded the business four years ago, had engaged in a Twitter exchange with the journalist Julie Burchill following the birth of the Duke and Duchess of Sussex’s second child.

Ms Burchill was sacked from The Telegraph over the exchange.

She had tweeted: “What a missed opportunity. They could have called it Georgina Floydina.” 

The barrister responded: “No Doria? Don’t black names matter?”

Ms Burchill said she “was hoping for Doria Oprah” – referring to Oprah Winfrey, who conducted an interview with the couple in March.

Ms Toch replied: “Doprah?”.

The Family Law Café said the comments were “offensive, unacceptable and highly contradictory to the inclusive manner in which FLC has always and will continue to work with members of all the communities in managing the challenges of matrimonial and family disputes”.

The Family Law Bar Association said Toch’s comments were “completely inappropriate and have no place in our society. Racism of any kind cannot be tolerated and cannot be justified as a joke.”
