Foxes lead the league by seven points
The Duke of Cambridge says he is "dying" for Leicester to win the Premier League.
He made the comments as he was presented with a cap to mark ten years in his role as president of the Football Association.
Leicester are currently seven points clear of second-placed Tottenham in the top tier with six games to go.
"I’m dying for Leicester to win. It will be good for the game," he said.
Prince William is an Aston Villa supporter with the club bottom of the table and heading for relegation.
He also called for the FA to "fully represent" society and serve the needs of modern football.
