Conservation charity the RSPB has apologised after calling PM Rishi Sunak and several of his ministers “liars”.
The charity said its “frustration” at the government “reneging on its environmental promises… led us to attack the people not the policy”.
The RSPB is angry at plans to scrap water pollution restrictions for housing developments in England.
The government says the move will be offset by other measures to tackle pollution.
It argues water pollution from new homes is “very small” and the change will mean up to 100,000 new homes can be built by 2030.
