Personally I think that the leadership of this country should be determined by making all the candidates take part in a weird combination trial with elements from the following:
1) Gladiator
2) Total Wipe-out
3) Takeshis Castle
and just to make things interesting
4) Come Dine with Me
5) Strictly Come Dancing
6) X Factor
The parties new leader will be whoever finishes with the most points.
In the event of a tie there will be a bonus round of
7) Snakes and Ladders
