The Prince and Princess of Wales' eldest son Prince George may only be nine, but the young royal, who is second in line to the British throne, is no doubt preparing for the moment he eventually becomes King.
Luckily, it seems Prince George already has the support of his younger sister Princess Charlotte, with the pair having charmed royal onlookers on several occasions by displaying their close bond at royal engagements. Royal fans have previously likened Princess Charlotte to Princess Anne, who has been a major source of support for her brother King Charles.
