When walkers John and Annette Taylor headed out for a walk on New Year's Day, they could not have predicted that they would end up on a hill with two of the country's most famous couples (and Michael Gove, for some reason). But there they were, along with baby Florence and a handful of welly-wearing strangers, at the Coombe Hill war monument near Chequers. They even posed for a picture. Here's our annotated guide to this unlikely band of ramblers:
1 Helena Bonham Carter Currently appearing as Bellatrix Lestrange, the villainous witch in the Harry Potter saga, Bonham Carter once shared a stage with deputy prime minister Nick Clegg in a play about Aids at Cambridge University, and it's believed to be through him that she and Burton first met the Camerons.
2 Tim Burton Burton's long-term partner Bonham Carter told one newspaper earlier this month that, in recognition of his services to the British film industry, "They should give him a knighthood. An honorary one would be fine." Which is not to say, of course, that that's why he and his wife were photographed on a hill with the prime minister. They just both love hills.
3 Michael Gove The education secretary looks rightly sheepish here, due in part to the continued outrage over his higher education cuts and in part because Bonham Carter is wearing a giant Christmas stocking as a scarf.
4 David Cameron On spotting him, Annette reportedly turned to her husband and asked, "Isn't that man with the baby a famous politician?" Yes, Annette, yes he is.
5 Florence Rose Endellion Cameron The latest addition to the Cameron family, appearing here in the guise of a pink mouse. Nancy and Arthur, the other Cameron children, are off doing their own thing. They presumably both hate hills.
6 Samantha Cameron Bonham Carter has said of her new friend Samantha: "She's a girl's girl who juggles more balls than a multi-armed Indian goddess." This is likely a reference to eight-armed Maa Durga, the Hindu goddess of circus skills.
7 Samantha Cameron's blue Converse Inappropriate footwear for hill-walking.
8 Absence of Nick Clegg Despite being the mutual friend who first united them, the Cleggster has clearly been frozen out of the Cameron-Bonham Carter gang.
9 Three other people These people aren't famous and are therefore irrelevant.
