The UK, as part of the EU, currently enjoys some of the highest standards for farm animal welfare in the world. But these welfare standards risk being diluted or sacrificed after Brexit unless assurances given by Government ministers become firm commitments written into UK Law. This Brexit Briefing spells out the gaps in animal welfare standards between the UK and its likely future trading partners, and specifies the measures that need to be put in place to protect animal welfare – and livestock farmers – as the UK leaves the EU. It has been written by Peter Stevenson, a lawyer and leading authority on international animal welfare regulation, who is also Chief Policy Adviser to the animal welfare charity Compassion in World Farming.
