Rachel Riley has won the first round in her libel case against a former staffer who worked in Jeremy Corbyn's office.
The High Court ruled that Laura Murray's tweet about the Countdown presenter, sent in March 2019 when she was stakeholder manager in Labour leader's office, was defamatory under common law.
The action centres on a tweet Ms Murray sent in response to a tweet Ms Riley sent after Mr Corbyn was egged by a Brexiteer when he visited Finsbury Park Mosque.
Ms Riley, who is pursuing Ms Murray for damages, had tweeted "good advice" and a thumbs up when she shared an earlier tweet by left-wing journalist Owen Jones, who wrote in January 2019: "I think sound life advice is, if you don’t want eggs thrown at you, don’t be a Nazi."
