First Minister Peter Robinson and his deputy Martin McGuinness are to meet the main Stormont party leaders today.
It is the first round-table talks since the share-out of departments in May.
A senior source described it as an attempt to improve communications between the parties amid criticism of the failure to agree a new Programme for Government and controversy over implementation of the four-year Budget.
In an Assembly debate yesterday SDLP finance spokesperson Dominic Bradley said Finance Minister Sammy Wilson had failed to reveal whether £1.6bn of additional revenue over the Budget period was new money.
“Is it merely from the sale of public sector housing and Housing Executive lands and other receipts which are usually available to Government? If not, perhaps the minister could tell us where this money comes from,” he said.
