Sheffield United chairman Prince Musaad Bin Khalid Al Saud has resigned from his position for personal reasons, the club have announced.
The 28-year-old became the Premier League's youngest chairman when he was appointed by his father-in-law, club owner Prince Abdullah bin Mosa'ad bin Abdulaziz Al Saud, in September 2019.
Prince Musaad leaves as the Blades sit bottom of the Premier League with 14 points from 31 games - with a possibility their relegation will be confirmed on Saturday.

"It has been an absolute pleasure and a real privilege to be chairman of this great club and I have always tried to uphold the values of the club and act as a true custodian," he said in a statement.
"To say I am disappointed how things turned out this season is an understatement. I have great faith that we have a bright future and I look forward to seeing everyone back at Bramall Lane in good health and cheering on our Blades."
Last month, manager Chris Wilder left his role after five years in the job, during which he guided them from League One to the Premier League.
Club owner Prince Abdullah said: "On behalf of the board of directors, I offer our thanks to Prince Musaad for his efforts, he has made a valuable contribution to the development of the football club."
Vice-chairman Yusuf Giansiracusa will take on the role of interim chairman.
