We’re sure we saw a headline today declaring that, given that they both appear on Time Magazine’s survey of the 100 most influential people in the world, that Kate and Pippa Middleton are the most influential sisters in the world. We don’t want to dwell on this one too much other than to query whether Hanne Thorning-Schmidt, whose little sister got voted in as PM of her country, is not doing perfectly well for herself whilst keeping a low profile. We’re more republican than royalist here but we’d point out by the same logic that Queen Magrethe of Denmark seems a definable polymath in her own right – whilst boasting a sister who was once Queen of Greece (and is still considered such by some). And that’s before you get to the non-Scandi Venus and Serena, whose stars are fading only in purely relative terms. Define ‘influential’.
