Brighton defender Ben White has signed a new four-year contract at the club until June 2024.
The Brighton academy product has also previously had loan spells at Newport County and Peterborough.
“I have been looking forward to working with Ben for a long time,” said boss Graham Potter.
“He was a player I was well aware of, even before I came to the club.
“He had a brilliant season helping Leeds to the title last season, and now he has the opportunity to show his qualities in the Premier League.”
