The Fylde Coast Multi Area Agreement, a deal between Blackpool Borough Council, Fylde and Wyre and Lancashire County Council, is due to be signed next month.
Phil Woolas, Minister for the North West, said: "It was due to be today (15 September) but the government thought it would be better if we didn't do the two on the one day. It was difficult to get everyone together because of the TUC conference at the Liverpool Convention Centre.
"When they planned the Liverpool City Region Multi Area Agreement final signing I don't think it was decided until later on that the Prime Minister was attending the TUC. So, I think it was felt better not to upset Fylde by cancelling the signing. We've got the agreement, it's just to do with logistics for the signing date, but I think it should be within the next month."
The deal will enable the councils in the area to pool funding streams to spend on sub-regional priorities.
The Multi Area Agreement will focus on improving transport links, boosting investment, and encouraging central government bodies to relocate to the area.
Blackpool's opposition to the Tithebarn retail scheme has reportedly been sited as a reason for the delay because the agreement was due to be signed off earlier this year.
The £700m plans, involving the creation of shopping space, gained planning permission from Preston City Council in July.
Minister Woolas was speaking at the signing of the second and final phase of the Liverpool City Region Multi Area Agreement at the Liverpool Tate yesterday afternoon.
Fylde Coast is one of the areas working with the government on Multi-Area Agreements, which includes Liverpool and Greater Manchester and Pennine Lancashire.
