One might think that would be true, but apparently it isn't. Here's some analysis I found: The belief that Scottish independence would consign the rest of the UK to permanent Conservative government is one that inspires hope among Tories and despair among Labour. But both overestimate the influence of Scotland on general elections. On no occasion since 1945 would independence have changed the identity of the winning party and on only two occasions would it have converted a Labour majority into a hung parliament (1964 and October 1974). Without Scotland, Labour would still have won in 1945 (with a majority of 143, down from 146), in 1966 (75, down from 98), in 1997 (137, down from 179), in 2001 (127, down from 166) and in 2005 (43, down from 66). I think the demise of Labour governments is just wishful thinking. I would expect the prospect of more Tory governments to squeeze the Lib-Dems, who are essentially left of centre anyway and merge their votes with Labour. You mean the "demise of TORY governments" surely, Rob?
