Probably poor timing for the SNP and other pro-independence forces; the electorate will have recently let off steam by kicking Labour really hard in May. Then again, it's hard to see them getting away with a referendum during 2009 or early in 2010, so I suppose it's a political necessity.
The Tories are a small party in Scotland (and Wales). In fact, the Tories winning the next general election in the UK will only help the yes for independence vote win the referendum. Scotland is undeniably to the left of England (A.K.A. Tory England).
Although the "United Kingdom of Great Britain [and NI]" might be a bit of a problem as a name.
Hehe, hopefully one day it will return to being just the "Kingdom of England."
