Yes, our Estelle has become a privy councillor. Hoorah! She follows her dad, Charles, and her troublemaking uncle, Lord Alf of Manchester (currently being a naughty boy over the welfare Bill) into the select club of advisers to the Queen which also includes cabinet ministers, high court judges and Commonwealth leaders.
The ceremony, we gather, involved swearing an oath while kneeling on a stool, then shuffling forward on her knees to kiss the Queen's hand.
The post comes with a costume - although there's no female version (the council used to be a bit of a boys' club). Still, as an official says: "Hardly anybody wears it these days ... but we do have a few outfits people can borrow."
