Arri GB managing director Renos Louka has resigned from the camera and lighting equipment manufacturer.
Broadcast understands that there are no immediate plans to replace the Arri veteran, who left earlier this month.
His departure follows long-term moves by the Munich-headquartered manufacturer to centralise its supply chain and management structure, a process in which Louka is understood to have played a key role.
The UK division of the firm, based in Uxbridge, reports directly to bosses in Germany, where half its 1,200 staff are based.
Russell Allen will continue to head up rental division Arri Media, which is also based in Uxbridge. Arri declined to comment.
