The impasse in the Northern peace process had to be resolved in a week or so, the Taoiseach told the House.

Mr Ahern said there was a last opportunity before the British general election to reach a conclusion of the current stage. There would be other stages, as the agenda unfolded over three, six or even nine years.

"There were issues not finalised in the Good Friday agreement, but which were not ignored. Policing was to be dealt with by the Patten Commission, decommissioning by Gen John de Chastelain and the Independent Commission on Decommissioning, and demilitarisation addressed by the British government when circumstances permitted.

"Other issues were the OTRs and the stability of the institutions, the latter the responsibility of the First and Deputy First Ministers.

"We have been trying to get an agreement on these issues within the five weeks. These are not all the outstanding issues, but they are important. To reach an agreed conclusion on these matters is our aim.

"We have not crossed every T and dotted every I, but there has been over 90 per cent progress. There are always differences of emphasis and opinion on what can be achieved.

"In the end the parties, collectively, but especially individually, have to decide what is satisfactory. The governments are working together and bilaterally with them to get everyone across the line in this phase. This has to be done over the next week or so."

Replying to the Labour leader, Mr Ruairi Quinn, the Taoiseach said no progress would create difficulties.

"There can be no such thing as the status quo in the peace process, as with a peace process anywhere. It cannot remain static. I accept that I have a role, as do the churches and others, in trying to persuade the parties if there is a deal which, although not perfect, can enable progress.

"We ourselves have not come to a conclusion yet but will decide soon. Everyone in this House realises the importance of progress. It is a difficult but important time.

"I hope that the parties in the North reflect on what has been achieved, and what has yet to be achieved."
