Strikingly, Labour's majority and vote share was higher than in the 1997 General Election. The Coalition parties saw their joint share fall from 58% to 44.7% (-13.3 on 2010). The swing from the joint LibDem and Conservative to Labour was 11.8%, which is similar to the current opinion poll standings.
This is the result for the major three parties (out of ten candidates).
Debbie Abrahams (Labour) 14718 42.1% (+10.2)
Elwyn Watkins (LibDem) 11160 31.9% (+0.3)
Kashif Ali (Conservative) 4481 12.8% (-13.6)
UKIP: 2029 (5.8%)
Monster Loony: 145
English Dems: 144
Bus Pass Elvis: 67
Labour majority: 3558
Turnout at 48% in a by-election held in the first fortnight in January has been higher than most commentators anticipated.
The Liberal Democrats are taking consolation from holding their vote share up. But election expert John Curtice has cast doubt on the importance of this, given that it seems to have been achieved through the collapse of the Tory vote share. This, Curtice argues, is a weak indicator of how most LibDem MPs will perform against Conservative opposition.
Curtice has told the BBC "it is a night of quiet pleasure for Labour if not necessarily riotous celebration" and a worrying result for the Conservatives.
Labour majority 103
