Small and medium-sized enterprises make a vital contribution to local economies, so I am delighted that in East Renfrewshire the number of registered enterprises has gone up by 18% since 2010. Does the Chancellor agree that as those businesses look to expand from being local to national players, it is vital to maintain the integrity of the UK internal market? Any moves to fragment it would damage the Scottish economy, place huge barriers to trade on both sides of the border, and put that vital contribution he just outlined in jeopardy.
