Andy King has been named caretaker manager of the Cobblers following the sacking of Aidy Boothroyd.
King was assistant to Boothroyd throughout his stint as manager at Sixfields, and will now stay on to take charge of first team affairs, starting with the Boxing Day trip to Burton Albion.
He will be assisted by goalkeeping coach Tim Flowers.
Boothroyd was sacked following the Cobblers’ 4-1 defeat to Wycombe Wanderers at Sixfields on Saturday, a result that saw them slump to the bottom of the Football League.
Chairman David Cardoza wasn’t at the game as he is on holiday, but his father Tony was in attendance, and Boothroyd was dismissed after meeting Cardoza Snr and his fellow directors.
The process is now underway to find a new permanant manager, but King has been handed the reins in the short term as the Cobblers face a hectic run of three matches in the space of seven days.
The Cobblers travel to Burton on Thursday, before going to Portsmouth on Sunday and then entertaining Chesterfield on New Year’s Day.
King previously managed Mansfield Town for three seasons between 1993 and 1996, and then Swindon Town from 2000 to 2005.
His most recent managerial post was at Grays Athletic, which he left in 2007.
Luton-born King enjoyed a successful playing caree which included spells with his hometown club as well as Everton, Queens Park Rangers, West Bromwich Albion and Wolverhampton Wanderers.
His first task as caretaker Town boss will be to galvanise the Town team following the disappointment of Saturday.
As well as losing the game, and then their manager, the Cobblers also saw midfielder Ian Morris and Mathias Doumbe leave the field through injury, and the pair must be doubts for the trip to the Pirelli Stadium.
It is going to be a tough test for King, as Burton are currently fifth in the Sky Bet League Two table.
They drew 1-1 at Hartlepool United on Saturday.
