SIR, AS your columns have shown, interest in the referendum has been sustained over two years: uniquely for a political issue.

I am Peebles born, raised in Innerleithen but living in the south of England. There are 300,000 Scots in London(2011 census) and they have been able to attend hustings, many of them well supported by both 'Yes' and 'No' campaigns. A feature of these have been the complaint that London Scots are denied a vote. I do not share that view: the decision properly rests with those living in Scotland and whose names are on the electoral register. Anyone though can participate in the debate.

I entered it initially in response to the consultation: arguing for inclusion of a question on extended devolution. However, as the Edinburgh agreement restricted voting to the proposition that Scotland should be an independent country, Scots are asked to make up their minds on that issue alone. I do not believe that the 'Yes' campaign has made a compelling case for the breakup of the UK. They have not been able to demonstrate how the advantages outweigh potential disadvantages. Three critical examples are: * Part 5 of 'Scotland's Futures' sets out the supposed benefits of independence in Q and A format, overall and then in seven specific areas of national life. Yet there is no adequate explanation of how these are to be secured or as to what difficulties must be overcome.

* Scotland's Futures' provides no analysis of risk: particularly in the critical areas where the co-operation of other governments and private sector businesses are concerned; a possible currency union; membership of the EU; persuading banks that it is safe to keep their administrative headquarters in an independent Scotland; and accession to NATO.

* Part 6 of 'Scotland's Futures' describes the proposed arrangements for Scotland's armed forces and diplomatic services. It is hard to see from this how these could represent better value for money than existing arrangements.

The case for retention of the Union is overwhelming as is that for a devolution of powers that will satisfy most Scots.

I am, etc.
