Loyalist Michael Stone has been jailed for 16 years for trying to kill senior Sinn Féin leaders in a one-man raid on the Northern Ireland Assembly.
Stone was convicted at Belfast Crown Court last month of attempting to murder Sinn Féin's Gerry Adams and Martin McGuinness at Stormont two years ago.
The 53-year-old former UDA member tried to enter the parliament building while the assembly was in session, armed with explosives, knives, an axe and a garrotte.
Television cameras captured the moment he burst through the revolving doors and was hauled to the ground by two security guards - both of whom were later honoured for their bravery.
Stone claimed his actions at Stormont were part of an elaborate performance art display.
In his judgement at Belfast Crown Court, Mr Justice Deeney rejected this claim as being 'wholly undeserving of belief'.
In 1989, Stone was sentenced to nearly 700 years for murdering six people, including three men killed in a gun and grenade attack on Milltown cemetery the previous year.
He was released from prison on licence in 2000 under the terms of the 1998 Good Friday Peace Agreement and went on to try to reinvent himself as a surrealist painter.
