Millwall have confirmed the appointment of Manchester City reserve-team boss Kenny Jackett as their new manager.
Jackett left Swansea by mutual consent in February of this year
Jackett, 45, will take up his role following Tuesday's League One fixture against his former club Swansea.
Jackett told the club website: "I'm excited to be joining. This is a club with tremendous potential."
Veteran defender Richard Shaw and coach Colin West had been in temporary charge of the Lions following the sacking of Willie Donachie on 8 October.
Chairman John G Berylson said: "Kenny has gained tremendous experience as a player, coach and manager. He has helped three teams win promotion as manager or assistant.
"His management skills are first class and I am confident he will soon have Millwall moving up the league."
