Charlton have announced the departure of manager Johnnie Jackson after seven months in charge.
Jackson took over as caretaker manager in October 2021 following the sacking of Nigel Adkins, with the side sat in the League One relegation zone with two wins from 13 games.
The former Addicks midfielder was then appointed as permanent manager in December 2021 and steered the club to a 13th-place finish in the league.
Charlton owner and CEO Thomas Sandgaard told the club website: “I would like to thank Johnnie for everything he has done for the club. He is a Charlton legend who has given his all for this club as a player, captain, coach, assistant manager and manager.
“I am grateful for all he has contributed during my time at Charlton, including stabilising us this season when he took over as manager, following our poor start to the campaign.
“This decision has been a very difficult one to make, Johnnie has done so much for the club, but I felt the time was right to make the change as we continue our preparations for next season.
“Our search for a new manager has begun. This season wasn’t the season any of us at the club wanted. I have big ambitions for Charlton and it will be important for us to find the right individual that can build on the foundations in place and help us progress on our journey.”
