Paul Lawrenson had part of an arm amputated

Ba'asyir was sentenced to 30 months for his part in the 2002 bombing that claimed the lives of 202 people.

The cleric is regarded as the spiritual leader of Jemaah Islamiah, the group thought responsible for the attack.

Sue Cooper, from Kent, who lost brother Paul Hussey in the blast, said only the death penalty was appropriate.

She continued: "It is disgusting. Anybody involved in the bombing should get the death sentence. He is just as guilty as the person who set it off.

He should have got the same punishment as the actual people who have been caught red-handed Paul Lawrenson Cleric jailed over bombings Sentence 'too lenient'

"He was the spiritual leader of JI. The British government should put pressure on the Indonesians."

She said the Foreign Office should have been quicker to inform her about Ba'asyir's sentencing.

Paul Lawrenson, from Swindon, who had part of his arm amputated after the blast, said there was no question that Ba'asyir should get the death penalty.

'No closure'

"It's far too lenient. He basically ordered or gave his blessing for it. He is a man of much influence.

"I'm very disappointed in the result. It doesn't say a lot for Indonesia's handling of the case. He should have got the same punishment as the actual people who have been caught red-handed, that means the death penalty."

Mr Lawrenson, a critic of the British government's slow response to the bombing, said it should now be making victims' opinions known to the Indonesians.

"It is my job and other survivors to keep the pressure on the government.

"I lost half an arm. It has affected me immensely."

Andrew Speirs, 67, from Bridge of Weir in Renfrewshire, whose son Stephen died in the bombing, said nothing could make up for the loss of his son.

"Whether they jail him for one year or 100 years it doesn't bring closure and it really doesn't matter in fact because we've lost our son and no jail sentence will ever bring him back."
