12.24pm: Theresa May, the home secretary, has just announced changes to police stop and search rules in response to a European court of human rights judgment earlier this year.
The police will not be allowed to use section 44 of the Terrorism Act 2000 to stop and search individuals, she said. Section 44 will only be allowed to be used to authorise the search of vehicles. Police officers who want to use the Act to stop and search individuals will have to use section 43 which - unlike section 44 - says officers have to have a "reasonable suspicion" that someone is a terrorist.
She also said that she was changing the rules so that police can only use the stop and search powers in the Act where it is "necessary" for the prevention of terrorism. Previously officers could use these powers were it was "expedient" for the prevention of terrorism.
Alan Johnson, the shadow home secretary, criticised the decision, which May announced in an oral statement in the Commonns. But it has just been praised by the Tory MP David Davis.
