Disgruntled police in Northern Ireland responsible for IRA leaks after Good Friday agreement

Newly released Irish archives include leaks from UK government and RUC's attempts to undermine Sinn Fein

Parts of the British government and disgruntled members of the Royal Ulster Constabulary were responsible for a series of major leaks during and after the establishment of the 1998 Good Friday agreement in Northern Ireland, according to claims in newly released Irish government archives.

An Irish department of foreign Affairs official focusing on justice and security created a report and list of the leaks in October 2002. They included attempts to undermine Sinn Fein, the republican political party linked to the IRA, and expose the position of the then Northern Ireland secretary, Mo Mowlam.
