Ex-environment watchdog chief defends move to Southern Water

Toby Willison has taken leading role at water firm due in court for sentencing after sewage dumping

A former chief of the environment watchdog has defended his move to take up a senior position at a water company that is under investigation by the regulator.

Toby Willison has taken a leading role at Southern Water, which this summer is due in court for sentencing after admitting dumping poisonous, noxious substances including raw sewage. The case followed a criminal investigation by Willison's former employer, the Environment Agency.
