Mike Cramp offered his resignation to Chairman, Joe Croker and the committee immediately after the full time whistle against Cray Valley on Wednesday night, which was reluctantly accepted.
The deflated Rusthall First Team recorded their 8th consecutive league defeat of the season.
The responsibility and managerial role will be assumed solely by Andrew McKechnie, who has been absent for the last few games, as he looks to turn the season around and re-inflate our squad.
Coaches Alan Murray and Alan Rogers will also continue their roles within the senior setup.
Chairman, Joe Croker and the committee would like to thank Mike for his commitment this season and wish him all the very best for the future.
