Theresa has played a clever game throughout - possibly relying on this precise scenario to propel her into Downing Street.
Whilst the Soubrys and Goves of the party go in opposite directions - there is a strong instinct for self-protection amongst the parliamentary tories.
Are there any likely to vote down a leader in a vote of confidence? - Quite possibly! Divisions run deep. It is precisely for this reason that a triumphant Boris, or indeed a Gove cannot be put in place any more than you could use a Ken Clarke or an Osborne clone as PM.

It is quite possible that there are others of this type who are less well known but Theresa seems to be leading the pack.
