The post you are reporting:
The official reason given by Murdo Fraser, Keith, is that the Conservative Party in Scotland does not attract a large number of potential votes that a centre-right Scottish party could achieve.
I believe the clue is in the enormous success enjoyed by the Scittish National Party, many of whose voters are unionists (for Britain), but wish to see decentralisation from the traditional establishment.
The move by Murdo Fraser, if he is voted as leader of the Scottish Conservatives, would see an independent party come to light, and possibly the end of the almighty-like power enjoyed by the Cabinet in London, which, at least in my view, is an essential part of the establishment when it comes to decision making in State policies.
Basicly, there would be more democracy in it for Scotland, without going the way of separation from the rest of Britain.
I daresay "leaderless Dave" will appear 3 inches smaller (in virtual terms) if Murdo succeeds!
