Ladbrokes have released there odds for the Bracknell Constituency General Election they are;
Conservatives 1/100
Liberal Democrats 50/1
Labour 50/1
UKIP 100/1
I think its worth a flutter.
Of course your MP may of been chosen already by a few hundred people at the Bracknell Open Primary/Caucus. The words Safe and Seat come to mind.
