Has Judy Murray Served Up Kate's Tennis Secret?

Judy Murray seems to have let the cat out of the bag by saying the Duchess of Cambridge is the new patron of Wimbledon. Kate joined Andy Murray's mother for a tennis training session in Edinburgh earlier, as part of a day in Scotland promoting her charities. There have already been reports that the Duchess is being lined up to take over from The Queen, who is the current patron of the All England Club, but it has not been officially announced.
