Under the plans, 10 live facial recognition (LFR) vans will be used by seven forces across England to help identify “sex offenders or people wanted for the most serious crimes”, according to Home Secretary Yvette Cooper.

The tech, which has been trialled in London and south Wales, will be subject to strict rules, the Home Office said, but human rights groups have warned it is “dangerous and discriminatory”.

Amnesty International UK said the plans should be “immediately scrapped”, with facial recognition proven to be “discriminatory against communities of colour”.
