The Norths' First and Deputy First ministers are today set to press British prime minister Gordon Brown to stump up the cash required for the devolution of policing and justice powers.
Peter Robinson and Martin McGuinness will also discuss progress on assisting savers in the ill-fated Presbyterian Mutual Society during the meeting at Downing Street.
Mr Brown has agreed to set up a working group to examine how investors can recoup the millions lost when the society went under late last year.
Devolved ministers have urged Mr Brown to provide the money needed to ensure that front line policing is not affected by the legislative move. However so far the prime minister has yet to table a firm offer.
Before meeting with the prime minister, the DUP leader and Sinn Fein deputy leader will meet Treasury officials at No 11 to discuss the PMS situation. Finance Minister Sammy Wilson and Enterprise Minister Arlene Foster will also be present for those negotiations.
The focus will then shift next door to No 10, where Mr Robinson and Mr McGuinness are scheduled to have a private meeting with Mr Brown.
