Back down to earth: David Cameron heads to hustings in Whitney

David Cameron on a train earlier today

After a whirlwind week of campaigning which has taken him to every corner of the country the Prime Minister is brought back down to earth by the British Parliamentary system tonight, Tim Bouverie reports. 

This evening Mr Cameron will be giving us a poignant reminder that we have a parliamentary system, not presidential like America. and because of this even as Prime Minister he will still have to do his own constituency hustings in a church hall in Witney, Oxfordshire. No cameras are allowed but you can hear the PM and the other candidates on Radio Oxford, if you happen to be in the area.
