The constituency that saved Gordon Brown’s premiership in 2008 will come under close scrutiny again in 2015 as the SNP eye one of Labour’s safest seats.
Standing down as MP following seven years at Westminster, Labour’s Lindsay Roy leaves behind a majority of almost 16,500 votes.
However, bolstered following the independence referendum, the SNP firmly believe they can snatch Glenrothes, buoyed by last month’s local council by-election which saw them take control of the town’s council affairs following a sizable swing from Labour.
The boundary of the constituency extends far beyond the town that gives it its name, taking in the Levenmouth area, Cardenden, and even a small section of northern Kirkcaldy.
Glenrothes has never slipped from Labour’s grasp before and given recent political developments, Lindsay Roy’s majority may yet be the party’s saving grace.
In 2008 the SNP tried and fell short.
This time, however, it is too close to call.The candidates* Peter Grant (SNP) The former Fife Council leader is attempting to make it to Westminster for a second time after failing to take the seat from Labour in a 2008 by-election.
