UK politics live – latest updates

Keir Starmer has suggested that Peter Mandelson should resign from the House of Lords and that the upper chamber should urgently modernise its disciplinary procedures to strip him of his peerage.

The cabinet secretary, the UK’s most senior civil servant, will also investigate Mandelson’s actions as business secretary when Labour was last in power, after emails to Jeffrey Epstein about government policy emerged.

Downing Street said that if Mandelson was called to testify before the US Congress inquiry into the Epstein files then he should, after a further huge tranche of documents was released over the weekend.
