Prince William has echoed the Football Association's call for the FIFA presidential election to be postponed.
The Duke of Cambridge, who is the FA's president, is "fully behind" the move, according to a St. James's Palace spokesperson.
Fifa president Sepp Blatter is set to stand unopposed to be elected for a fourth term after his only rival, Mohamed Bin Hammam, was forced to withdraw after being suspended amid bribery allegations.
FA chairman David Bernstein has admitted its attempt to have Wednesday's election postponed is almost certain to fail.
But a statement on Tuesday evening said that Prince William "is fully supportive of the chairman and the initiatives the FA has recommended.
"He considers the transparency of the international governing body to be integral to the good governance of the game."
Bernstein insisted a "coronation" of Blatter is unacceptable and he also wants Fifa to appoint an independent body to supervise reforms following the claims that have caused a crisis in the world governing body during the last month.
