The environment secretary, George Eustice, insisted the government was tackling the millions of hours of raw sewage discharges into rivers and seas in England as MPs demanded answers to a summer of water companies dumping effluent into holiday swimming spots.
Caroline Lucas, the Green party MP for Brighton Pavilion, said: “Literal shit is being pumped into our rivers and seas. The state of our water network is a national scandal and the government has utterly failed to take action.”
