The Sinn Féin president, Gerry Adams, has said that the British government must rein in those within policing and security in the North who want to damage the peace process.
He was speaking after the Northern Secretary, Peter Hain, rejected calls for a public inquiry into the Stormontgate affair and revelations that one of the three defendants accused of spying was revealed as a British agent.
Mr Hain said the affair is just another blip in the process but, after a meeting between the two, Mr Adams gave the incident a much higher importance.
"A very unique power-sharing administration was toppled. After centuries of conflict a process was being coaxed into a new dispensation and the truth of the matter is that British agencies were at the heart of the coup d'etat..so that is not a bump in the road," he said.
