Queen of England and Prince Philip have demonstrated their faith in Prince William's abilities as future king by handing him two new important royal roles. 

During William's lifetime, he will almost certainly see his father become king. Only if Charles dies before the queen would William become king when the queen dies." This means that if Prince William becomes the King of England, Middleton will become the Queen of England. Here's how the royal couple have endorsed their grandson.

Queen Elizabeth II and Prince Philip, each have hundreds of royal patronages and on Monday it was announced they had handed two of them down to their grandson Prince William, 38. William is heir to the British throne and will take the crown following his father Prince Charles, 71. In recent weeks, the Duke of Cambridge has demonstrated his dedication to tackling environmental issues, making him a good fit for his two new royal patronages.

The Queen was patron of the Fauna & Flora International (FFI) for more than 70 years but has now handed the special post to William. Prince Philip, was patron of British Trust for Ornithology (BTO) for 30 years before passing the role down to his grandson.

Despite retiring from royal life in 2017, the Duke of Edinburgh still has dozens of royal patronages which may continue to be passed down to younger Royal Family members in time.

Commenting on Prince William's new appointments, one royal commentator claimed it was a sure sign of the Queen and Philip's faith in their grandson's "abilities".
