The 2015 UK election result 2 days early.

Here is my final forecast; An absolute dead heat. The incumbent Tories (being the party holding power now) attempting to stay in power with a minority government. Labour will make a Queen's speech which will be voted on and therefore they will be given the keys to number 10........but but but, they also will not be able to maintain a minority government and will concede to a second election, either in July! Or in November.
What happens in that next election is simply those that voted for the 'other' parties will have to choose from the main 3 parties if they wish to have a functioning government. The choice is theirs!
