After months of legal wrangling, the proceedings will last seven days and will be sure to include revelations that will fill front pages for the entire week.
But what exactly is Rebekah Vardy suing Coleen Rooney for and how much do we know about the two women at the centre of the 'Wagatha Christie' trial?
A timeline of events: How did the public row between the two women unfold?
September 2017 to October 2019 – The Sun newspaper runs a number of articles about Mrs Rooney, including that she travelled to Mexico to look into baby “gender selection” treatment, her plan to revive her TV career and the flooding of her basement.
October 2019 – Mrs Rooney uses social media to accuse Mrs Vardy of selling stories from her private Instagram account to the tabloids. After sharing a series of “false” stories and using a process of elimination, Mrs Rooney claims they were viewed by one Instagram account, belonging to Mrs Vardy. Mrs Vardy, then pregnant with her fifth child, denies the allegations and says various people had access to her Instagram over the years.
June 2020 – It emerges that Mrs Vardy, who, according to her lawyers, suffered from extreme distress and anxiety because of the publication of the post, has launched libel proceedings against Mrs Rooney.
November 2020 – The libel battle has its first High Court hearing in London. Mr Justice Warby concludes that the “natural and ordinary” meaning of the posts was that Mrs Vardy had “regularly and frequently abused her status as a trusted follower of Mrs Rooney’s personal Instagram account by secretly informing The Sun of Mrs Rooney’s private posts and stories”.
April 2022 – Mrs Vardy “appears to accept” that her agent Caroline Watt was the source of allegedly leaked stories, Mrs Rooney’s barrister David Sherborne tells the High Court.
He argues that a new witness statement submitted by Mrs Vardy suggests Ms Watt was the source but Mrs Vardy claims she “did not authorise or condone her”.
