My hon. Friend makes the point very powerfully.
Sixthly, new arrangements should ensure that no new regulatory barriers develop between Great Britain and Northern Ireland, unless agreed by the Northern Ireland Executive and Assembly. That commitment was made in paragraph 50 of the joint report by negotiators from the European Union and the United Kingdom Government in December 2017. Our Government sadly failed to honour that paragraph when they concluded the Northern Ireland protocol. We expect that commitment, which was made by the Government, to be honoured.
