LONDON — Prime Minister David Cameron and his wife got home from lunch with friends at a pub in the English countryside to discover they had forgotten something: 8-year-old daughter Nancy.

Nancy was fine — she was quickly reunited with her parents after they realized she was missing. But Cameron’s parenting skills took a drubbing Monday, just weeks after the government set up a program to give parents of young children classes on how to raise them.

Downing Street said the incident happened “a couple of months ago” as the family was leaving a pub near Chequers, the official country house prime ministers use when they want to escape London.
