The Taoiseach will meet British prime minister Tony Blair at Downing Street next week, with Mr Ahern insisting yesterday that talks on restoring the North's political institutions cannot wait until a report due in January on the level of IRA activity.
It is understood that the Government has not ruled out a meeting with the DUP also taking place in London next Tuesday, although a spokeswoman said yesterday that no arrangement had been made.
Mr Ahern will meet the SDLP and Alliance Party in Dublin tomorrow and is to meet DUP and UUP delegations shortly.
The Taoiseach told the Dáil yesterday that he was determined to make progress in talks about restoring normal politics in the North before next January's crucial report from the Independent Monitoring Commission (IMC), which assesses the level of paramilitary activity.
"The next report of the Independent Monitoring Commission will be published this month," he told the Dáil yesterday.
"This will give an indication of progress on the ending of IRA paramilitary and criminal activity. There will be a further IMC report in January.
"I hope these reports will confirm IRA paramilitary and criminal activity has ended," the Taoiseach added.
He condemned the recent attacks on Dr Paisley's Martyrs Memorial Church on Belfast's Ravenhill Road, and attacks on several Orange Halls in Co Antrim.
He said he acknowledged some loyalists felt themselves to be alienated, but that "we must continue to point out that the Good Friday agreement is about restoring institutions.
"We should not wait until the second IMC report is published in January to restore institutions. We must continue to work and make the effort between now and then."
He said he and Mr Blair had scheduled meetings with the various parties in Northern Ireland. They will review the outcome of these meetings at next Tuesday's meeting in Downing Street.
"The second IMC report will be crucial," he told the Dáil. "If all is not well there will not be too much talking to be done.
"If all is well, however, I hope that we will be able to get into really meaningful discussions on getting the institutions up and running," the Taoiseach said.
