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 £109million 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. The company notified the Stock Exchange last week after a 13 per cent hike in its share price. There were also smaller rises in shares of other water companies.
