I think he's ambitious for his own sake but I don't think he really cares about the country long term. I base that on the fact that his wife didn't pay tax here until it threatened his career and that he retained a US green card as a "plan B" for after he'd finished being in power.
Would he want it now? I'm not so sure. I thought they were gunna keep Truss in over winter and replace in the new year when the worst of the energy crisis has passed.
There you go. But took the opportunity to buy the pound after it crashed at one of it lowest levels and made a killing out of it, rather than screaming here over a lettuce.
Everyone saw that resignation coming after the rejection of their tax cuts by the markets.
