Prime Minister Andy Burnham apologises after he refers at Prime Minister’s Questions to an “individual” who is “responsible for the murder” of former Tory MP Ann Widdecombe. Widdecombe died at her home in July. At the time of Burnham’s comment, the court case is still at an early stage and no plea has yet been entered.

The man at the centre of the case, Joshua Kerry, 28, was arrested on suspicion of murder on July 11 and is due to face a High Court trial before a judge on 8 June next year. Multiple outlets report that Kerry last week appeared in court facing an additional allegation relating to preparing terrorist acts, including allegations involving Nigel Farage. Burnham’s comment draws criticism from Conservatives, who say it effectively treats a person awaiting trial as already convicted, breaching the presumption of innocence.

While MPs speaking in the Commons are protected by parliamentary privilege, sources also note the existence of a sub judice convention that discourages MPs from referring to matters still awaiting adjudication. Commons leader Sir Alan Campbell says Burnham acknowledged he misspoke, apologised, and corrected the record, while other figures argue misstatements could mislead the House.
