So what have we learnt in the last week?
It started with 12 and now there are 6, what happened.
Anyone else notice that all the women are out!
In the first ballot of Conservative parliamentarians last week, former foreign secretary Johnson received 114 votes, more than double his nearest rival, the current Foreign Secretary Jeremy Hunt, who received 43. Environment Secretary Michael Gove was in third place with 37 votes.
Mark Harper, Andrea Leadsom and Esther McVey were eliminated after receiving fewer than 17 votes, and Matt Hancock dropped out on Friday, saying he accepted that the party was not looking for a “fresh face”.
International Development Secretary Rory Stewart has become a surprise star of the race, rising to second place this week. He was named the winner of Channel 4's debate.
