Fresh tensions emerged today between Sinn Fein and the Democratic Unionist Party (DUP) over the transfer of policing and justice powers from Westminster to Stormont. The issue which once threatened the future of the power-sharing government in Northern Ireland appeared to be edging towards agreement after British Prime Minister Gordon Brown brokered a £1 billion deal on financing the process. But despite Mr Brown's exhaustive negotiations, relations between the parties hardened today with republicans accusing the DUP of trying to squeeze concessions on Orange Order parades before allowing a deal to go ahead. Sinn Fein has accepted the Prime Minister's financial offer, but the DUP has said action needs to be taken to secure unionist community confidence in the devolution of the powers. Democratic Unionist leader Peter Robinson told the House of Commons this week that uncertainty over the future stewardship of loyal order parades in Northern Ireland should be resolved ahead of a deal and he called for the scrapping of the Parades Commission which currently rules on controversial marches. The removal of the Commission has been a long-standing unionist goal and Sinn Fein President Gerry Adams today accused the DUP of trying to make it a precondition of a deal on devolution.
