Boris likes the IDEA of leadership more than leading. Same as he seems to like the idea of relationships more than being in them.
He just likes 'winning', and people seeing he's 'won'
He wants to be loved. He wants to be acclaimed. He wants to be envied.
He DOESN'T want to actually do anything himself.
Now don't get me wrong: there are certain circumstances when that can be quite useful. AS LONG AS the people actually doing the work are smart, and manage upwards.
Most prominent example: The London riots, when Boris refused to cut his holiday short then panicked and Half-arsed the response until Theresa May stepped in as Home Sec.
He has to use Tory politicians. Worse, the kind who would agree to serve under a glory leach.
What terrifies him is the thought of having to do the work
