My right hon. Friend is rightly addressing the rule of law in a particular negotiation. Will he recognise, however, that the negotiations we are conducting around the world, including with the Japanese Government and the beginning of the conversation with the comprehensive and progressive agreement for trans-Pacific partnership will rely on the UK making deals that will endure the future? Those deals will only endure truly if the UK holds together and values all parts of this United Kingdom. Will he recognise, therefore, that his role is to promote the voices of Scotland, England, Wales and Northern Ireland together to make sure all those four nations achieve the best for the whole United Kingdom?
