A quick thought on Carswell

By not simply crossing the floor at Westminster to join UKIP, but resigning and calling a by-election to do it, has he now set a precedent for any other Tory MPs who want to do the same? The last MP to do that for a defection was Bruce Douglas-Mann switching from Labour to the SDP in 1982 (and he lost), and MPs who’ve done it since then haven’t followed his example.

However, if there are any other Tories thinking of doing the same (and there probably are), they’ll be watching what happens in Clacton very intently as they know that if they want to switch, they’ll face lots of questions about why they’re not calling a by-election too. Indeed, a cynic might suggest that Carswell has found a way to establish himself as UKIP’s only MP (with the resulting media profile) should he win and if no one else wants to take the same risk.
