Good evening. The Duke of Sussex has made an extraordinary intervention into politics, claiming that the Government is at “rock bottom”. We have all the key updates from the High Court, as Prince Harry gave evidence in his case against Mirror Group Newspapers.

Prince Harry used the witness statement he lodged in a High Court case against a tabloid newspaper to liken the state of the Government to that of the press. 

The 55-page statement was released as he began giving evidence in the case against Mirror Group Newspapers (MGN) over unlawful information gathering, including phone hacking. 

The Duke, who is pursuing a separate legal action against the Government over his security arrangements, broke with convention by wading into politics, writes our Royal Editor Victoria Ward.

In his statement, Harry attacked Piers Morgan who left Good Morning Britain for saying he did not believe claims made by the Duchess of Sussex during her and Harry’s explosive Oprah Winfrey interview. 

The Duke alleged Mr Morgan, the former editor of the Daily Mirror, had been intimidating him and his wife since he launched legal proceedings against the publisher of the Mirror newspaper.
