Unlike his own father who had private tuition in a nursery at Buckingham Palace, Prince William attended Mrs Mynors nursery school in London while Kate went to a nursery school in Amman in Jordan where her father was working.

The nursery is located in a private road which the royals hope will deter prying eyes. William is particularly sensitive about press intrusion after his mother Princess Diana was killed in Paris in 1997 when her limousine crashed into the wall of a tunnel as they tried to flee a posse of chasing photographers.

In August, the royal family criticized the paparazzi for what it called increasingly dangerous attempts to photograph George when he was out with his nanny in London parks.
