New coronation portrait of King Charles III with Prince William, Prince George released by Buckingham Palace

King Charles III posed with his son and his grandson Prince George -- the two heirs to the throne -- in an official portrait released by Buckingham Palace.

Charles became king immediately after the death of his mother Queen Elizabeth II in September after 70 years on the throne but was officially crowned last Saturday in a ceremony showing off the full pomp and pageantry of the British monarchy. 

Hugo Burnand, who also took four other official coronation portraits that were released on Monday, told Hello! magazine he wanted to show the line of succession.
