Police forces, including the Met, have agreed to adopt a new government code of conduct on the use of their powers to stop and search members of the public.
Scotland Yard will publish data on each stop and search conducted after concerns the powers were being misused.
Tougher rules have been proposed for the controversial “section 60.” This rule allows police to stop and search anyone where there are no grounds of suspicion, this was recently used at Notting Hill Carnival.
In one million of the searches carried out last year, more than 250,000 could have ben illegal.
The changes come after Her Majesty’s Inspectorate of Constabulary found that 27 per cent of stop and searches did not contain reasonable grounds for suspicion.
Under a new scheme, 'Best use of Stop and Search’, the result of each stop will be recorded to see how many lead to an arrest.
