Gillingham’s former first team coach Mark Robson has joined League 1 side Peterborough United.

Robson was named Gillingham’s assistant manager when Andy Hessenthaler was appointed boss last month but he left after just three weeks citing "personal reasons".

He joins The Posh as coach under manager Gary Johnson.

Robson was brought to the Gills by former boss Mark Stimson in August 2008, having served for several years as part of Charlton Athletic’s back-room staff.
