On your first day, I want to give you some advice.

(And Andy, though we’ve been friends for 30 years, I need to call you PM because that’s who you are now, and you need to get used to the title, the status and the power.)

I have seen prime ministers up close. I worked for Tony Blair in his final years in office as his political secretary.

I ran a group of those who stayed loyal – “The Non-Embittered Former Ministers”.

But you start with a full tank of authority. Use it! Quickly and decisively! The cruellest judgment on Donald Dewar after the first 100 days of running the newly devolved Scottish Parliament was that he “hit the ground dawdling”.
