Police have released details of a 999 call involving the theft of a mobile phone belonging to Morgan McSweeney, Sir Keir Starmer's former chief of staff, according to reports from multiple news outlets.

McSweeney left his position as chief of staff last month, with his departure linked to his role in vetting processes within the Labour leader's office.

The phone theft has raised security concerns, as the device reportedly contained communications between McSweeney and Peter Mandelson, the veteran Labour politician. A Cabinet minister has described the loss of these exchanges as a significant error.

The release of details about the police call appears to have created tensions between law enforcement and Downing Street officials, though the specific nature of these disagreements has not been fully disclosed.

The incident highlights ongoing security challenges faced by senior political figures and their staff, particularly regarding the protection of sensitive communications and information stored on personal devices.
