Milton Keynes Dons have parted company with manager Robbie Neilson, with assistant manager Stevie Crawford and first-team coach Neil MacFarlane also leaving the club.
The decision, which was made during a meeting between the club chairman Peter Winkelman and Neilson on Saturday evening, comes after MK Dons lost 2-1 away at Northampton.
MK Dons are 21st in League One having won just once in their last 11 league matches.
Neilson took charge in December 2016, replacing Karl Robinson, after spending two years as Hearts manager.
The 37-year-old joined MK Dons with the club only two points above the relegation zone and guided them to a 12th-place finish.
In a statement, the club said: "Robbie, Stevie and Neil have all been totally dedicated to MK Dons, working tirelessly throughout their 13 months at Stadium MK.
"We thank them and everyone at the Football Club wishes them every success in the future."
