The government is hoping to secure parliamentary backing for a long-term counter-terrorist strategy in the face of what Tony Blair warned yesterday was a "very real" danger of Islamist terrorism in the UK lasting for at least a generation.

Mr Blair said he fully supported an assessment by Eliza Manningham-Buller, director-general of MI5, the Security Service, that there were 30 plots at various stages of planning in the UK and 1,600 people identified as potential supporters of terrorists acts.
