The heir to the heir to the heir to the British throne has taken a big step up the educational ladder.

Kensington Palace said that Prince George started nursery school Wednesday, a milestone for the young future king.

Prince William and his wife Kate marked the occasion by releasing two photographs of two-and-a-half-year-old George outside the school building.

The royal couple had earlier announced he would be attending Westacre Montessori School in Norfolk, 110 miles north of London.

The school has said he will receive the same treatment as other pupils.
