In my opinion, divergence brought about by devolution enriches the fabric of the Union, but the divergence we are talking about could, in a very real sense, undermine the integrity of the United Kingdom's common market. I have had emails from constituents that regularly begin with the words: “I believe that Brexit should strengthen devolution for Scotland, not weaken it.â€ Many other Members will have had similar emails. I want my constituents to know that that is exactly my position. I want a Brexit that strengthens the democracy of our country and strengthens the devolution settlement for Scotland. I ask Ministers, in the summing up at some point tonight, to make it clear again that the Bill guarantees the existing devolution settlement and the existing powers of the Scottish Parliament and promises that there will be more powers to come. In regard to the tone and manner in which this issue is discussed and debated, I wish to pay tribute-SNP Members will not be surprised to hear me say this-to Ruth Davidson, Professor Adam Tomkins and others, who have worked as honest brokers in this process, by working with the Scottish and UK Governments to bring them together to build consensus. I believe consensus is vital for the new constitutional settlement we need to reach. I welcome the recent change of tone from the Scottish Government, especially from the First Minister. When she came out of Downing Street on her last visit to London, I thought she had some very positive things to say. As a Scot, I welcome that: I welcome the fact that the First Minister of my country is willing to be a positive contributor, rather than a simply a detractor. I want take this opportunity to express my full confidence in the approach and style of the First Secretary of State and the Secretary of State for Scotland, who are leading the UK Government in the very important talks with the Scottish Government. I have great confidence that there will come out of the discussions an agreement that will be sustainable because it will be built on consensus. Consensus is not gained by shouting matches or feigned indignation-we see quite a lot of feigned indignation in this place-and all I would say is thank goodness the SNP leadership in Edinburgh has more maturity than some of the MPs it sends to London. I remain hopeful, and I am optimistic.
