Taoiseach Bertie Ahern British Prime Minister Tony Blair are to urge Northern Ireland's politicians to speed up the process of restoring power-sharing during their visit to Belfast tomorrow.
Sources have indicated that both men will tell the Rev Ian Paisley and Gerry Adams the November 24th deadline for devolution must be met.
After six tetchy weeks since the Northern Ireland Assembly was recalled, Mr Blair and Mr Ahern will also map out a timetable for political progress ahead, at a round of meetings with Stormont Assembly parties.
A source said: "This was always going to be a difficult introductory period for the Assembly. Nevertheless there is a Preparation for Government Committee, the Whiterock Orange parade last weekend passed off peacefully when last year didn't. It is important to recognise these as progress.
He repeated however, that both governments were insistent that the November deadline is cast in stone and that the parties need to "up the pace over the summer and into September".
"The governments will therefore be setting out how we see the timetable for September to November."
Taoiseach Bertie Ahern heaped on the pressure today saying he believed the Assembly would not be restored before the end of the decade in the absence of agreement by the November 24th.
"If we're not going to get these institutions up and running in the long term, we're not going to get them up in the medium or short term either."
Devolution was suspended in October 2002, and the North is now run by a team of British ministers.
Mr Blair recalled the Assembly in May in the hope that parties would be able to built up trust and confidence in each other.
However, it has been dogged by a Sinn Fein boycott of debates and by regular clashes with the Democratic Unionists on a committee tasked with identifying key issues which have to be addressed before November.
Sinn Féin wants the governments to make it clear tomorrow to unionists that they have a clear plan to implement all other aspects of the Belfast Agreement if the deadline is not met.
The DUP insists it will not be forced into power-sharing and continues to insist it needs to be satisfied that the IRA has ended all violence and criminality and are committed to democratic politics.
Northern Ireland Secretary Peter Hain warned in the House of Commons today that Assembly salaries and allowances would end if the deadline passed.
"There is no reason for the parties not to negotiate on the restoration of devolved government and to achieve it before the deadline of November 24 which is a deadline set in statute, set in concrete.
"If it's not achieved, the salaries will end, the allowances will end and the financial assistance to political parties will end, totalling some stg£600,000.
