Who will be the Weakest Link?

EXPLANATION OF IDEA
The party leaders would be contestants of "The Weakest Link" game show. They would be asked questions about british history, culture, legislation and current world news headlines. After all, who wants a Prime Minister who is clueless about these things?

The quiz would be televised live and the public would vote after each round for the candidate who answered most questions incorrectly. Votes would be by telephone.

The last 2 candidates would battle head to head and the person with the most correct answers in this final round would be the Prime Minister.
