Negotiations remain in the early stages, and we do not expect the two clubs to conclude a deal at the current price suggested.
Saints have attached a higher value to Charles, 22, after he impressed with key goals in the FA Cup and Championship play-offs.
The Northern Ireland ace got the extra-time winner against Middlesbrough in the play-off semi-final to send Saints to Wembley in May.
However, the club never got to play the final due to being booted out of the competition after admitting to spying on three Championship opponents.
Failure to reach the Premier League has weakened Southampton's position as they hope to retain key players ahead of the 2026/27 season.
Leeds have made a ÂŁ20m-plus offer for Charles as they look to bolster their squad following a 14th-place Premier League finish last campaign.
Former Manchester City prospect Charles joined Saints in 2023 for an initial fee worth ÂŁ10.5m with potential add-ons rising to ÂŁ15m.
He has made 76 appearances for the club since that summer move, and spent the 2024/25 season on loan at Sheffield Wednesday.
Charles has previously been linked with a move to Everton and Manchester United, and recently registered an assist against France.
