The UK's Environment Information Regulations have enabled researchers and campaigners to force water firms to publish data on river pollution, but they may be scrapped as part of the Brexit process.

REUL: Scant time remains to assess which former EU legislation to keep, amend or revoke – and the environment is likely to pay the price. / While we were EU members, the UK adopted some legislation created by the EU. Jacob Rees-Mogg called them “diktats” and promised that after Brexit we’d “take back control of our laws”. This is disingenuous: the UK was fully involved in drawing up EU law.

Did you know that many of our environmental laws - from how we manage our fisheries, to standards on marine pollution, to how we protect many species and habitats - come from the European Union?
