The Conservative Party voting system is quite simple. MPs vote for their preferred candidate and the candidate with the fewest votes is eliminated. Repeat until there are just two candidates left. At that point, all Party members vote for their preferred candidate, the winner becoming party leader.

Is it possible for the Conservative Party’s conservative wing (supporters of David Davis and Liam Fox, for example) to vote tactically so that Ken Clarke does not make it to the final two?

Maybe the excess Davis vote can ensure that Fox is never the last-placed candidate by voting for him. When we get to, say, three remaining candidates could that knock Mr Clarke out?

Could they arrange it so that the final battle is between Mr Fox and Mr Davis?
