With more pollsters producing more general election polls than ever before, there is a lot of interest in the final vote shares that parties will secure.
To tap into this Ladbrokes has produced an interesting market on whether the three main parties will get above or below specific thresholds in Britain, excluding Northern Ireland.
These have been set at 40% for the Tories, 30% for Labour and 20% for the Liberal Democrats.
Given current polling, the best bet must be on the Liberal Democrats reaching the 20s but the odds are just 8-11.
If you want something with a better return try the Tory bet at 11-10 against them being above 40%. As we get closer to 6 May there will be a squeeze on the smaller parties, particularly Ukip, and this, surely, will help David Cameron.
