PARIS (Bloomberg) - Banco Santander SA, Spain's biggest bank, is trying to resurrect talks to combine its US business with M&T Bank Corp. after negotiations collapsed last month, said three people with knowledge of the matter.

Santander and M&T recently scheduled a meeting between the banks' top executives, two of the people said, speaking on condition of anonymity because the matter is private. The banks' leaders still disagree on who would control the combined firm - the issue that led the discussions to break down in May, the people said.

Before talks fell apart, Santander had been discussing a stock merger of Sovereign and M&T in which Santander would end up with a minority stake in the unit, said one of the people.

Santander was seeking a deal that would allow it to eventually gain control of the combined bank, a move that M&T resisted, this person said.

Spokespeople for Santander, M&T and Allied Irish declined to comment.
