Prince William has urged Wales to beat England in the Rugby World Cup on Saturday so that he can have the bragging rights over his brother Prince Harry.
William is vice president of the Welsh Rugby Union and Harry holds a similar role at the Rugby Football Union.
"Unfortunately, I will be watching you with my brother, so I will need a Wales win more than ever," William said at the Wales welcome ceremony in London.
"Whilst we have been dealt a very tough group stage, I firmly believe that, with a simple, determined, match-winning mindset, this team can progress into the knockout stages and beyond. I look forward to having plenty to cheer about throughout the tournament.
"We now need to look to the rest of the group and particularly this Saturday's match. This will be one of the biggest clashes of the tournament and certainly of the group stages."
Both teams won their opening match of the tournament, with Wales thrashing Uruguay and England overcoming Fiji.
