The Bostik League North club have confirmed that Spencer and Holland will take on the role of joint-managers from now until the end of the season when all parties will review the situation going forward.
Chairman John Martin told the club`s website: "Having discussed the position with other senior officials of the club, we felt it was in our best interests at this time to appoint Billy and Michael as managers.
