Ireland politics since the Agreement has been the eclipse in electoral terms of parties such as the SDLP and Ulster Unionist Party (UUP), by rival parties such as Sinn Féin and the DUP. Similarly, although political violence is greatly reduced, sectarian animosity has not disappeared. Residential areas are more segregated between Catholic nationalists and Protestant unionists than ever. Thus, progress towards restoring the power-sharing institutions was slow and tortuous. On 8 May 2007, devolved government returned to Northern Ireland. DUP leader Ian Paisley and Sinn Féin's Martin McGuinness took office as First Minister and deputy First Minister, respectively. Collusion between security forces and paramilitaries There were many incidents of collusion between the British state security forces (the British Army and RUC) and loyalist paramilitaries. This included soldiers and policemen taking part in loyalist attacks while off-duty, giving weapons and intelligence to loyalists, not taking action against them, and hindering police investigations. The De Silva Report found that, during the 1980s, 85% of the intelligence loyalists used to target people came from the security forces, who in turn also had double agents and informers within loyalist groups who organised attacks on the orders of, or with the knowledge of, their handlers. Of the 210 loyalists arrested by the Stevens Inquiries team, all but three were found to be state agents or informers. The British Army's locally recruited Ulster Defence Regiment (UDR) was almost wholly Protestant. Despite recruits being vetted, some loyalist militants managed to enlist; mainly to obtain weapons, training and information. A 1973 British Government document (uncovered in 2004), Subversion in the UDR, suggested that 5–15% of UDR soldiers then were members of loyalist paramilitaries. The report said the UDR was the main source of weapons for those groups, although by 1973 UDR weapons losses had dropped significantly, partly due to stricter controls. In 1977, the Army investigated a UDR battalion based at Girdwood Barracks, Belfast. The investigation found that 70 soldiers had links to the UVF, that thirty soldiers had fraudulently diverted up to £47,000 to the UVF, and that UVF members socialized with soldiers in their mess. Following this, two were dismissed. The investigation was halted after a senior officer claimed it was harming morale. By 1990, at least 197 UDR soldiers had been convicted of loyalist terrorist offences and other serious crimes, including 19 convicted of murder. This was only a small fraction of those who served
