A new package of counter-terrorism measures which will be proposed by the government on Monday would outlaw those who provide or attend terrorist training courses in Britain or abroad and make it a criminal offence to describe those who carry out suicide bombings as martyrs.

The centrepiece of a counter-terrorism bill will be the new crime of "acts preparatory to terrorism", which ministers said yesterday would make it easier for the police and security services to intervene when a terrorist operation was being planned. The package will be discussed in cross-party talks at Downing Street next week.
