Bugsy,

On election day broadcasters in the UK are required to impose an almost total blackout on any strictly political discussion commencing an hour before the polling staions open until they close and certainly can't discuss the results of any early exit polls

This leaves a bit of a vacumn and, after the effects of the weather on turn out have been exhausted, someone inevitably asks the question why are elections conventionally held on a Thursday?

The only 'explanation' that the BBC were able to offer was that, as people were tradionally pad a weekly wage on a Friday, this was the best way of securing a sober electorate!

Another often quoted reason is -
'the government is formed on a Friday, and then everyone has a weekend to absorb the change and for the government to prepare for work.'

That doesn't always work either :)
