If the Parliamentary timetable for the Queen's speech is to be believed, then Parliament should reconvene on Tuesday 18th May and the Speech would be on Tuesday 25th May.
I wonder if this will be possible given the current blip in continuity, whilst some post election introspection takes place? What's the shortest time between elections? Someone will know. I'll hazard a guess at six months, so maybe 25th November would be a round six months from the speech making and could see a new Parliament up and running for 2011?
That's enough time for parties to re-organise and perhaps a more balanced set of voting practices to be devised.
All the politicians are pointedly saying they are working for the "National Interest" now, rather than their own agendas, so perhaps anything related to improving the representation of the people could be on their minds, rather than their own self-promotion?
