Having watched the Tories tragic approach to tactics over this term in government, I agree, intelligence is not a talent they possess. Whether the timing is right or not is irrelevant to the outcome. She will always have to come to the point of convincing the rank and file that she is the best choice they have.
I think Cameron is going to be a much bigger catalyst for a change in direction for the Tories than people are seeing atm. All the focus will be on Greensill and how he dragged us out of the EU. While forgetting he is now in charge of Foreign policy, and being an ardent remainer. Is this a turning point for what Sunak believes? There is one thing that is certain, polling will change direction as Tory voters will flood back under Cameron. But will they flood back before the party implodes is the question. Time to microwave some Popcorn.
