At nine this morning I was on protocol duty downstairs, waiting to welcome Dutch Princess Laurentien to the ‘art and climate change’ event I wrote about yesterday. The security services stood beside me as we awaited the Princess and her escort. At about five past nine a Mini with Dutch number plates drove into sight and parked by our back door. Out popped the princess, who had driven herself. She has always been committed to literacy (she is the UN Envoy for Literacy) and cultural causes and generated considerable media interest last year when she published a children’s book, Mr Finney and the World on its Head, designed to educate children to be environmentally aware. It was a lovely and unepexcted start to a very, very busy day.
