The Government announced action yesterday to outlaw those who glorify terrorism, as it emerged that one of the suicide bombers who killed more than 50 people in London visited Parliament last year as the guest of an MP.
Hazel Blears, the police minister, issued details of sweeping new anti-terrorism laws to be introduced in Parliament this year.
She said that radical preachers who supported suicide bombers could be caught by a new offence of "indirect incitement to commit terrorist acts".
Indirect incitement could include "people who seek to glorify terrorism acts, perhaps by saying: 'Isn't it marvellous this has happened; these people are martyrs.' " Such comments could be seen as an "endorsement of terrorism".
In a letter sent to the Tories and the Liberal Democrats, the Home Office also proposed to make it an offence to provide or receive terrorist training in Britain or abroad and to create an offence of committing acts preparatory to terrorism.
Next week Tony Blair will meet Michael Howard, the Tory leader, and Charles Kennedy, the leader of the Liberal Democrats, in the hope of reaching cross-party consensus on the proposals, which will be included in a counter-terrorism Bill.
David Davis, the shadow home secretary, said: "This appears to be a very sensible start. We support the principle behind these plans."
