Sinn Féin President Gerry Adams has categorically rejected new claims that he authorised the murder of an IRA double agent Denis Donaldson in 2006, writes Daniel McConnell of the Irish Examiner.
Mr Donaldson was killed in Co Donegal shortly after he publicly revealed he was a British agent, a move which led to the collapse of the institutions in Stormont.
The fresh claims were contained in a BBC Spotlight programme broadcast last night.
The programme included testimony from an anonymous IRA agent referred to as 'Martin' who himself worked as an RUC agent from 1997.
In a series of meetings with the makers of the programme over a series of months, Martin claimed that the killing was sanctioned by Mr Adams.
Martin told the programme that he had been told that the IRA had killed Donaldson, despite the organisation's denials at the time.
The programme claimed that it was sanctioned on foot of a request from republican Thomas 'Slab' Murphy and other leading republicans in South Armargh for the purpose of maintaining army discipline.
Martin claimed that murders had to be approved by the political and military leadership of the IRA which meant Mr Adams.
In a statement to the programme, solicitors for Mr Adams said he totally rejected the claims insisting he had no knowledge of or involvement in the killing outside Glenties.
He denied he had the final say in sanctioning the murder.
No one has ever been convicted of Donaldson's killing.
Earlier this year, two men were arrested in connection with the murder of Mr Donaldson. He was shot dead at Cloghercor, Doochary, Co Donegal, in April 2006, in a killing claimed by the Real IRA.
Months earlier it had emerged that the Sinn Féin member had worked as an agent for the police and MI5 for 20 years.
Both men were arrested in the Donegal area and are currently being detained at Letterkenny garda station under the provisions of Section 30 of the Offences Against the State Act.
