The chief executive of Ofwat has accused Thames Water of a "catalogue of failures" over sewage spills.
The regulator has proposed fining Thames Water, Yorkshire Water and Northumbrian Water a total of 168 million pounds after conducting an investigation.
David Black adds Ofwat is talking to the government about giving them additional powers to block chief executive bonuses "where companies fail to comply with the law".
