The next government must give Windermere greater protection from sewage pollution, campaigners including the naturalist Chris Packham and the comedian Paul Whitehouse have urged in an open letter to all party leaders.
The campaign group Save Windermere, which organised the letter, says the lake has huge ecological significance, is home to rare and protected species and brings in about £750m to the economy. But the signatories, who include the Wildlife Trust, the countryside charity the CPRE and WildFish, say it is being degraded by pollution.
