This comes after Sadiq Khan, London’s Mayor, was under increasing pressure to clamp down on violence crime.

After six killings within four days, and 59 this year, Tories charged the Left-wing leader with doing “next to nothing”.

Kit Malthouse was a former minister of police and asked for Khan’s consideration to introduce tougher measures than those introduced by Boris Johnson as London mayor.

Mr Malthouse, now Chancellor of the Duchy of Lancaster, told LBC radio station that London ‘has been plagued by knife crime in the past and seems to be in the grip of it again’ – adding: ‘I just hope that the mayor starts to take this as seriously as we did all those years ago and leans in hard.’
