Adams gives backing to talks
Party president Gerry Adams said Sinn Fein was committed to a full and productive role in achieving a conclusive resolution to the current impasse.
But he claimed it was unacceptable to allow the Democratic Unionist Party to dictate the pace of progress.
“The decision by the governments to put off intensive negotiations until September means that they have bought into the time-frame set down by the DUP,” he said.
“Once again the governments are allowing unionism to set the pace in the process. This is unacceptable.”
The British Government announced on Friday that it planned to hold a review of progress ahead of intensive negotiations in September.
Mr Adams said there was no reason to delay efforts to resolve the deadlock for the summer.
The planned discussions, involving Tony Blair and Bertie Aherne, are due to be held next Friday to review progress and assess the situation before intensive negotiations in September in a bid to restart the Belfast Assembly.
The devolved assembly at Stormont was suspended in October 2002 amid allegations of an IRA spy ring operating at the Northern Ireland Office.
At the annual Wolfe Tone commemoration parade in Bodenstown, Co Kildare, Mr Adams said republicans had the political will to reach a comprehensive deal.
“Sinn Fein believes that it is possible to achieve a comprehensive and holistic package, which deals with all of the outstanding matters in a way that is definitive and conclusive.”
Mr Adams also attacked the Labour Party in the Republic for courting a possible future coalition with Fine Gael.
