UK Prime Minister Theresa May yielded to pressure from hardliners in her own party on Brexit, agreeing to accept all of their amendments to new trade legislation. During votes on the bill in the House of Commons, the government accepted four amendments backed by the European Research Group (ERG), whose members oppose the Brexit plan agreed by the cabinet. The ERG said the changes would prevent the UK collecting duties on behalf of the EU after Brexit and make the government's "facilitated customs arrangement" impossible. However, Downing Street said the amendments were consistent with the government's position.
