Talks involving the Irish and British governments and the North's main parties continued today at Stormont with no sign of a breakthrough in the political deadlock.
The SDLP and Sinn Féin earlier claimed the main difficulty still lay in DUP demands for changes to the Good Friday Agreement.
The two governments have been co-chairing talks with the main parties at Stormont since yesterday. The discussions are aimed at resolving the issues outstanding after the Leeds Castle deliberations last week.
Mr McGuinness said he thought it would be difficult to resolve all the issues blocking the return of devolution, but he insisted the negotiations were not yet bogged down.
The Northern Secretary, Paul Murphy, and Minister of State for Foreign Affairs, Tom Kitt, put forward a position paper yesterday on how they believe the deadlock can be broken.
