THE chairman of Ulster Bank has said delays in the Government sell off of TSB could squander an opportunity. Sir George Quigley said he hoped his company would soon acquire TSB and contribute to increased competition in banking. His remarks came as difference of opinions within the Labour Party were delaying a decision on the future of the TSB. Informal proposals by the Minister for Finance, Mr Quinn, have not been approved by some of the parliamentary party, and there is thought to be disquiet in some trades union circles about a sale.
