NAPOLEON famously preferred lucky generals. As Chancellor of the Exchequer, Rishi Sunak has had lots of luck. He got the job unexpectedly when his predecessor, Sajid Javid, fell out with Dominic Cummings. Sunak was no sooner ensconced at Number 11 when Covid arrived. He met the emergency by literally printing money by the billion, thus avoiding the necessity of raising taxes or cutting expenditure. For a Chancellor, this was a godsend.
