However my next question would be so what if he is? You don't think May is arrogant? I couldn't imagine a more arrogant Prime Minister with her nonsensical Brexit Means Brexit, no early election and then expecting the population to just shut and an accept she can do what she likes and say what she likes.
Now personally I don't know her so i'll refrain from definitely labelling her arrogant. Maybe it is an act? However the UK has been destroyed by Thatherite policies. So a question of arrogance isn't important. That's personality and the leader of a nation doesn't have been a great personality.
Do you want another set of Thatcherite policies to further dismantle the UK? Which leader has a nicer personality is hardly even important.
