Just checked his Wiki and he's 78 next year, to my surprise.
Including the current Home Secretary, there are 18 living individuals who have held that office. Almost enough for a DDP theme team!
Half of them are aged 70+... Douglas Hurd (94), Kenneth Baker (90), Ken Clarke (84), Michael Howard (83), Jack Straw (78), David Blunkett (77), John Reid (77), Charles Clarke (74), Alan Johnson (74). I wouldn't be surprised if we lost a couple of these by the end of 2025.
Both Ken Clarke and Charles Clarke (no relation to our non-British friends) have always struck me as prime heart attack territory. Douglas Hurd has lasted a long time... 95 in March, not seen in public anymore. Should be on the Deathlist next year.
