London is to get a disaster "blueprint", outlining what should be done in the event of an attack or similar catastrophe.

Minister for London Nick Raynsford has been asked by the government to review current emergency procedures and to chair a new committee that will create the contingency plan.

Membership of the committee is still being decided, but Mayor Ken Livingston will play an important role in the

new arrangement, having last week demanded urgent clarification about who would take the political lead if an emergency occurred in London.

Any disaster response in London would be co-ordinated by Scotland Yard's special operations room and, in some circumstances, the Home Office would step in to approve military support from barracks across London.
