A radical Islamist group that planned a march through Wootton Bassett will be banned under counter-terrorism laws, Home Secretary Alan Johnson has said.
Members of Islam4UK had planned the protest at the Wiltshire town to honour Muslims killed in the Afghanistan conflict.
The government had been considering outlawing the group - Islam4UK is also known as al-Muhajiroun.
Earlier this week, Gordon Brown said plans for the march were "disgusting".
Mr Johnson said: "I have today laid an order which will proscribe al-Muhajiroun, Islam4UK, and a number of the other names the organisation goes by.
'Tough but necessary'
"It is already proscribed under two other names - al-Ghurabaa and The Saved Sect.
"Proscription is a tough but necessary power to tackle terrorism and is not a course we take lightly.
"We are clear that an organisation should not be able to circumvent proscription by simply changing its name."
On Sunday Islam4UK cancelled the march and issued a statement from spokesman Anjem Choudary, saying it had "successfully highlighted the plight of Muslims in Afghanistan".
"We at Islam4UK have decided, after consultation with others including our Sheikh Omar Bakri Muhammad, that no more could be achieved even if a procession were to take place in Wootton Bassett," he said.
The group denied members had planned to carry 500 empty coffins through the town.
The banning order will come into effect on Thursday and make it a criminal offence to be a member, punishable by up to 10 years in prison.
