Sky news reporting that Javid's votes mostly appear to be going to Johnson and Gove. If Hunt beats Gove then it will suggest Johnson votes being lent to Hunt. If it's a secret ballot then I don't understand why they reveal numbers after each round (apart from satisfying people's/media's curiosity). The best way to avoid tactical voting would be to only announce who is through and who drops out and then only release the numbers for each round after the final two are confirmed.
Not that it matters. Johnson could turn up at the regional hustings with a pair of underpants over his head and two pencils up his nose and still win the members' vote.
