Now to the big questions, namely, what will William and Harry wear for Sunday's riverboat pageant?

Clarence House has confirmed that the young Princes will wear military uniforms, but won't say which, and the young Princes certainly have a wide choice.

Although Prince William and Harry are both serving Royal Air Force men, the pressure will be on, says Tim Walker in today's Telegraph, "to dust down their rarely worn naval attire for the celebration of Britain’s maritime history".

"Harry is Commodore-in-Chief of Small Ships and Diving, while William is Commodore-in-Chief, Scotland, and Commodore-in-Chief, Submarines.

"William caused some surprise on his wedding day when he did not marry in RAF uniform, instead choosing that of the Irish Guards. He had only been appointed as the regiment’s Royal Colonel a couple of months earlier by the Queen."
