On the morning of April 18th, when the election was announced, I happened to be passing Abingdon Street and saw the odds on a party getting the most seats were:
Con 1/10
Lab 6/1
Lib Dem 25/1

On the eve of the election, passing the local betting station, I see that the odds for getting most seats are now:
Con 1/20
Lab 8/1
Lib Dem 500/1

Here in Oxford and West and Abingdon, on Paddy Power, the odds on the 4 parties winning are
Con 1/5
Lib Dem 11/4
Lab 100/1
UKIP 200/1

The Green Candidate decided to stand down at this election as some greens will be lending their vote to the Lib Dems.
