Ian Paisley and Martin McGuinness are due to meet British Chancellor of the Exchequer Gordon Brown in Edinburgh today to push the case for a generous "peace dividend" in the North.
Mr Brown has already promised a major investment package if a stable power-sharing Executive is re-established at Stormont.
The North's politicians are seeking a generous package of financial aid, including a lower corporation tax rate to encourage foreign investment.
The last time they went to see Mr Brown about the matter, they expressed disappointment with what was on offer.
Dr Paisley and Mr McGuinness, the new First and Deputy First Ministers at Stormont, will be hoping for more from today's meeting, which is also being attended by the incoming Finance Minister Peter Robinson and Regional Development Minister Conor Murphy.
