Gove was education secretary in Cameron's government and his advisor was Dominic Cummings, who styled himself as the great disruptor, tear it all down, throw everything in the air etc. etc. - it's easy to pigeonhole Cummings as just an arrogant git but I think he's much worse and has a genuine messiah complex.
I think Gove showed his true merit when he distanced himself from Cummings and stopped trying to overcomplicate everything he touched. I'm not a Tory and don't agree with him, but he was an able minister.
He's now left his wife and to coin a phrase "seems to be going through some stuff" - he had been very friendly with Kemi Badenoch but she stopped speaking to him when she set him up with a friend of hers, who he pumped and dumped. Allegedly. Also, at 56 he's probably working on the assumption that the Tories will be out of power for a decade and by the time they get back in he won't be considered for a cabinet post due to his age.
