The boss of Wakefield-based shirt-maker Double Two says his company is keen to expand its operations and is on the lookout for a major acquisition. Last year the company was thwarted in its attempt to buy rival shirt company Van Heusen from Coats Viyella. But according to Double Two managing director Ricky Donner, the firm is now looking for a substantial acquisition of a UK-based clothing business to complement its existing operations.
