ANGLIAN Water's parent company, awg Group, has confirmed that it had received an approach that could lead to a takeover bid or merger. The group's profits trebled to \u00A3109million in the year to April, the company announced last spring. It would not name the suitor from which it had received a preliminary approach that might or might not lead to a formal bid, it said.
