The result of this Westminster by-election were seen as a litmus test of the parties' standing prior to the 2007 Scottish Parliament election; the Liberal Democrats proceeded to win the Dunfermline West seat, which comprises the bulk of Dunfermline and West Fife, from Labour in the 2007 Holyrood election. The results of all by-elections in Scotland have been particularly highly valued by psephologists and political commentators since the demise of the last regular, monthly Scottish voting-intention poll (by "The Herald" and Taylor Nelson Sofres System 3) at the end of 2003. The result was also notable as it came at a time when Labour's national opinion poll ratings were very high.
