I'm sorry but how come there so many by-elections each week ? O_o
In France we only have 2 or 3 cantonales or municipales by-elections per month. Is the UK more willing to cancel election results or do UK elected officials tend to die more ?
Deaths are the most common. There are resignations and what not but it's the whole growing old (or indeed not so old) which does it
It averages out - I think we get about 5 by-elections a week, every week, but sometimes it's a Hell more and sometimes much less. Rarely, if ever, is there a blank week.
