Bad night for the Tories, but I don't think they will be tremendously surprised. Wakefield totally expected but the Tiverton loss is worse than expected though and will raise alarm bells in Conservative HQ.. Labour will probably be a little wary too, as their vote collapsed - no doubt they don't mind on this occasion, but a resurgent Lib Dems would pose concerns elsewhere. As with all by-elections mind, it's probably not worth over-analysing it.
