Pretty average by-election result for a party mid-way through their 3rd term with a big economic downturn happening. The Labour vote held up well, just over 30%.
It's normal for a government to lose a mid-term by-election. It's what the Liberals/SDP/Lib Dems have depended on for the last 35 years.
What's different here is that it's the main opposition party who are winning the anti-government vote. This isn't normal. This happens when the opposition is in with a good chance of winning a general election. It's a serious result.
