Despite fear of another Bradford West-style upset, Labour comfortably won all three of yesterday's by-elections, in Rotherham, Middlesborough and Croydon North, retaining each seat on an increased share of the vote. But the real story of the night was how well UKIP performed and how poorly the Lib Dems did. Aided by the child fostering row, Nigel Farage's party finished second in Rotherham, winning 21.79 per cent of vote, up from 5.9 per cent in 2010 and its best-ever result in a Westminster seat. UKIP also came second in Middlesbrough and third in Croydon North.
By contrast, it was another terrible set of results for the Lib Dems. The party finished eighth in Rotherham (behind the BNP, Respect, the English Democrats and an independent), the worst result any major party has suffered since 1945, and lost its deposit after winning just 2.11 per cent of the vote. It also lost its deposit in Croydon North, where it finished fourth (behind UKIP) and won 3.5 per cent of the vote. The Tories also performed poorly, finishing fifth in Rotherham (behind UKIP, the BNP and Respect), the party's worst performance in any by-election in this parliament, and fourth in Middlesbrough (behind UKIP and the Lib Dems).
Having talked up its chances in Rotherham and Croydon North, Respect didn't come close to threatening Labour. Indeed, in the latter, the party actually lost its deposit after Lee Jasper, Ken Livingstone's former equalities adviser, finished sixth with 2.9 per cent of the vote. Respect performed better in Rotherham, where it fielded Yvonne Ridley, a former journalist who converted to Islam after her capture by the Taliban, and finished fourth with 8.34 per cent.
Given the disadvantages faced by Labour in Rotherham - Denis MacShane's resignation over false invoices, a divided local party , and, most recently, the UKIP fostering row  - the party will be pleased that it managed to increase its share of the vote from 44.6 per cent to 46.25 per cent, a swing of 6.5 per cent from the Tories, who finished second in 2010. Few ever expected Labour to lose any of the six by-elections held this month but that the party performed well in each case is firm evidence of its increasing strength.
