Aveley have parted company with manager James Webster by mutual consent just weeks before their play-off campaign begins.
The Millers have confirmed their place in the top five with five games remaining of the season, but are now rudderless.
Webster stepped down as Brightlingsea Regent manager in October 2017 to join Aveley after taking the R’s from the Essex and Suffolk Border League to the Bostik League Premier.
He won the Bostik North title by 14 points in 2016-17 with Brightlingsea and has Aveley in promotion contention.
However, Webster won’t be seeing out the season. A club statement confirmed: “An increased workload has led to James being unable at present to dedicate himself totally to manage our football club.
“It is with reluctance all parties have come to this decision.
“The club wishes to thank James for him time at Parkside and wish him all the best for the future.”
