Britain is investing in 30,000 more electronic tags for criminals as part of a massive overhaul in sentencing law.
The huge expansion of tagging technology will see nearly 40,000 criminals electronically monitored at once.
Justice Secretary Shabana Mahmood is understood to have secured £700 million in funding from the chancellor, Rachel Reeves, to buy the devices.
This will increase the Probation Service's budget by roughly a third and enable it to quadruple the number of criminals fitted with electronic tags, The Times reports.
It comes as David Gauke, the former Conservative justice secretary, will publish a long-awaited sentencing review this month.
