SIR TERENCE's successor, Andrew Turn- bull, must try to put this machine into order. Charlie and the back-seat kids will tangle with him at their peril. The Chancel- lor cannot be seen to fall out with two per- manent secretaries, one after the other, and Mr Turnbull is known in Whitehall as a ruthless opponent. Sir Terence came into Whitehall by a side door — he was teaching at the London Business School when Geof- frey Howe brought him in as chief econom- ic adviser — but Mr Turnbull might have been born there. I remember seeing him in front of the House of Commons Treasury committee, which wanted to know how much harm had been done by some cuts in the Treasury's collection of statistics. Owing to the cuts, Mr Turnbull replied, the answer to this question was not available. Sir Humphrey Appleby would have been proud of him.
