The Poppies' boss has this morning announced his resignation from the club after guiding them to the Southern League Central title last season.
A statement on the club's official website reads: "The football committee today have accepted the resignation of Marcus Law.
"Marcus oversaw the development of the first team squad during his 4 seasons at KTFC, culminating in promotion last season back into the National League North.
"All at KTFC wish Marcus well and thank him for his commitment."
Law's replacement was immediately announced as ex-player and former Nuneaton Borough manager Nicky Eaden as the man to lead them next season.
“Nicky has the qualities we are looking for in a manager," club owner Ritchie Jeune said.
"A player who has played at the level and who has had the success that Nicky had during his playing career, including winning the league we are currently in, he knows what it means to win and more importantly what is needed from the top down to win.
"Nicky has had a challenging start to his managerial career, I believe that Kettering Town FC is the right club for Nicky to excel”.
Eaden wasted no time preparing the club for their first campaign back in the National League North, signing on eight players on Saturday morning.
