A new joint statement has been agreed between Prime Minister May and the European Commission, which supplements the Political Declaration signed in November 2018. The commitment to non-regression on environment, social and employment standards is in the same spirit with the Political Declaration’s provisions. The only difference appears to be the terminology used: “non-regression” replaces the previously used “level playing field”.
