More than 200 people who have served varying sentence types are set to be tagged by March 2026.
Sadiq Khan is also investing an initial £50,000 to help ensure the management of stalking cases on the new pilot.
There will also be greater information sharing with partners, including the Met police, Probation Service, the NHS and the Suzy Lamplugh Trust.
The Trust was set up following the disappearance of estate agent Suzy Lamplugh in Fulham in 1986.
She was officially declared dead, presumed murdered in 1993 and her body has never been found.
The latest data from the Mayor’s knife crime tagging programme shows 67% of tag wearers successfully completed their period of monitoring up to a maximum period of six months.
A third had been recalled to prison with GPS tracking data playing a significant role in the detection of non-compliance and new offences in recalled cases.
The Mayor’s GPS Domestic Abuse Tagging Pilot has also tagged 707 high-risk individuals released from prison since 2019 and analysis from the Mayor’s Office for Policing and Crime (MOPAC) found improved risk management, improved protection for victims and more effective enforcement of licence conditions when these are broken.
Following the success of this pilot, MOPAC has worked with the Ministry of Justice to support their new national electronic tagging programme.
