You’ve been warned:

Gordon Brown’s wife Sarah is ready for her next adventure. ‘The last adventurous thing I did was go travelling with my girlfriends — Sandi Toksvig and Kathy Lette — and we walked the Cornish coastal path,’ she tells me. ‘We’re plotting our next long walk, which I’m really looking forward to. We’re going to try to be more adventurous this time though — maybe Scotland or round the North of england.’
