David Cameron appoints an Australian nanny with royal ambitions The post of nanny to David and Samantha Cameron would probably have been enough even for Mary Poppins. The family of Sammi Strange, the attractive Australian who has just won the job, wonder, however, if this may not lead to even greater things. David Strange, her father, says she enchanted her new employers in video interviews after an agency put them in touch. He says that, before her interview, she was told only she was being considered by a "high-profile" British family. "She was shaking when she found out it who it was," says the former vice-president of an Aussie-rules football club. She was very excited and nervous. I'm hoping she might marry Prince Harry, but I, seriously, couldn't afford the wedding. Sammi, 24, was born in Melbourne and previously worked as an advertising sales assistant. She is understood to be introducing the couple's three children - Nancy, eight; Arthur, six; and Florence, 18 months - to Australian culture and has passed on a gift from her father: a rugby-shaped Aussie rules football. I trust Sammi will take care, too, of the signed cricket bat that was presented to Nancy by the Indian cricket star Sachin Tendulkar. David Cameron told a 1,200-strong audience at the Westminster launch party of Conservative Friends of India that he was dismayed when he found Samantha playing French cricket with it in the gardens at Chequers during the warm weather. "I said, 'No, darling, put it down, this is probably the most valuable possession I have," " he said.
