Sunak just saw the opportunity to further himself I think. He was never really that interested in the role. It was all about finance and power.Europe and Johnson killed the party. Howard and IDS were completely useless and Hague should of waited post Blair landslide.
But Brexit made them go complete bannanas on their Brexit by any cost strategy. Johnson throwing out all the moderates just left the idiots and they had no talent remaining. Sunak I just don't get his view he was a leader for 10-15 years time when they had a chance at power again.
