Derry republican Tony Taylor is set to take his case back to parole commissioners after spending more than two years behind bars without charge or trial.
He has been detained in Maghaberry Prison since in March 2016 after his early release licence was revoked by then secretary of state Theresa Villiers.
He was sentenced to 18 years in jail in 1994 for IRA activity and again for three years in 2011 for possession of a rifle.
In June last year parole commissioners refused to release him from prison.
It is expected his case will go before the commissioners again in the coming weeks.
His solicitor Aiden Carlin said campaigners are hopeful he will be released.
"There is a legitimate expectation that Tony Taylor shall be re-released on licence,” he said.
“His continued detention without trial has been raised by the Irish government and his release called for by councils north and south."
Meanwhile, Co Armagh republican Gabriel Mackle was released from detention by parole commissioners earlier this month.
His early release licence had been revoked by the Department of Justice last November.
