(Telegraph paywall) Boris Johnson is taking a big gamble by pulling back from the Conservative leadership race
http://www.telegraph.co.uk/news/2017/06/22/boris-johnson-taking-big-gamble-pulling-back-conservative-leadership/
Prince Harry says no member of the royal family really wants to be king or queen,
but the same can never be said of the Conservative Party.
Unlike the monarchy, the line of Tory succession is crowded and disorderly.
There are at least a dozen MPs who have their eyes on the Tory crown,
some of whom are right now contemplating regicide 
.....
Boris Johnson, whose unruliness must make him the Conservatives’ Prince Hal, has said he will not stand for leader until after Brexit is completed in March 2019.
.....
In the wake of the election result Johnson had been flooded with messages from MPs pledging their support if he wanted to challenge for the leadership. 
< shows how many wingnuts are in the Tory party >
His latest comments suggest he has reached some sort of deal with David Davis, 
whom many MPs want to take over as a caretaker leader if the Prime Minister finds herself unable to carry on.
It was convenient, of course, for Johnson – a former journalist – to create a story of his leadership plans out of his interview with Channel 4 News
because this partially eclipsed coverage of his faltering performance earlier in the day on Radio 4’s PM programme,
during which he struggled to explain what was in the Queen’s Speech and at one point was heard to be rifling through his notes as he sighed “hang on a second”. 
Philip Hammond remains the most dangerous Cabinet threat to May
.....
Over the past week, by giving interviews in which he lamented the failure of the Tory election campaign to focus on the economy,
the Chancellor made clear both his intention to stand for leader when the time comes
and to put the PM on notice that she must be more conciliatory and let Cabinet ministers speak their minds.
Now that Hammond has marked May’s card,
now that some pressure has been released from the party’s valves,
he has backed her to stay in Downing Street for the time being.
Hammond said on BBC Breakfast on Thursday morning that she would still be PM by the end of the year.
Thoughts of another Conservative leadership contest this summer,
at a time of uncertainty over Brexit, concern over terrorism and the need for the government to get to grips with safety in hundreds of tower blocks across the country after the Grenfell fire,
< i.e. wait until the public forgets who keeps cutting safety regs and the fire brigade >
are receding from the collective mind of Tory MPs.
Graham Brady, the chairman of the 1922 committee, has collected 10 letters from MPs declaring they have no confidence in May,
but there is some way to go before that number reaches 48, the threshold needed to trigger a leadership challenge.
If May does step aside before the end of the year,
Johnson’s decision to delay his ambitions and the lack of appetite for a contest
now make Davis the next in line to the Conservative throne.
< or maybe a DD vs Hammond contest >
It is another question entirely whether Davis, who has long cherished becoming Tory king,
would regard himself as a mere caretaker
who would abdicate in March 2019 to make way for Johnson.
