Bank of Scotland is attacking rival Natwest takeover bidder Royal Bank of Scotland by questioning the BoS links with insurer CGU.
BoS chief executive Peter Burt is putting a series of questions to RBS on its relationship with CGU in a statement to the London Stock Exchange.
The move by the insurer to buy a stake in Royal Bank has led Natwest to argue the bank is jeopardising long term benefits for shareholders.
Burt says: “The question for shareholders is whether RBS is sacrificing shareholder value for short term support in its eagerness to make a major acquisition. Is RBS giving CGU access to a massive customer franchise too cheaply?”
