Former defence secretary accuses PM of putting UK’s security at risk at a time of growing international threats

Keir Starmer’s premiership has been pushed to the brink of collapse after the shock resignation of John Healey as defence secretary undermined his security credentials and risked shredding his remaining political authority.

In a blistering resignation letter, Healey accused Starmer and his chancellor, Rachel Reeves, of putting the country’s security at risk, saying the long-awaited defence investment plan (Dip) fell well short of what was required.
