Labour has no real plan to tackle the sewage crisis damaging Britain’s rivers, leading campaigner Feargal Sharkey has warned as he called for a “root and branch” review of water industry regulators.

The punk rocker turned environmentalist told i the country needs a “clear, decisive strategy” to clean up Britain’s waterways rather than “the confusing messaging” coming from the Government.

His comments came as he announced plans to lead a mass rally in London in October to mark the end of Labour’s first 100 days in power and put pressure on the chancellor ahead of the Budget.
