Republican prisoner Seamus McGrane, 64, died of a heart attack while serving a sentence of 11.5 years in prison.
McGrane was an old fighter for the liberation of Ireland. He had been imprisoned for the first time as a member of the IRA in 1976. He was imprisoned a second time in 2001 for organizing an underground training camp with a shooting range.
He was one of the founders of the Real IRA and, allegedly, planned a bomb attack during Prince Charles’s visit to Ireland in 2015.
The Prince’s tour included a visit to the spot in Co Sligo where the Provisional IRA murdered Lord Louis Mountbatten and three others in 1979.
McGrane was only the second person to be convicted of directing terrorism in the Irish Republic. The first was Michael McKevitt, who was jailed for 20 years in 2003.
McGrane was one of the dissident republicans in the Provisional IRA who led a walkout from the organisation’s “army convention” in October 1997. Alongside McKevitt – the brother-in-law of IRA hunger striker Bobby Sands – McGrane founded the hardline anti-ceasefire Real IRA.
