Bamber Bridge chairman Terry Gammans has shocked fans by stepping down from the role.
His departure comes a month after manager Tony Greenwood left Irongate.
Brig finished 11 points off the play-offs in seventh this season, and also reached the final of the Lancashire Trophy.
Gammans said it was a tough decision but he needed to concentrate on his business interests.
He said: “Before I took over as chairman, I’d seen Brig play a few times before, but I wasn’t sure what it was going to be like.
“In the last five years, there have been many trials and tribulations but it has been a great journey.
“As a kid I grew up watching teams like Crystal Palace and Chelsea, but I wasn’t the world’s greatest footballer.
“I was always the last one to be picked for football at school – if picked at all.
“I’ve met some great characters in my time here. It’s something I will always look back on – I’ve enjoyed every minute of it.
“It has certainly been a fantastic family thing as I’ve taken my wife, grandchildren and my father to the matches.
“I just felt it’s time as I’ve got a new business venture coming up which will mean I won’t give the club the full attention it deserves.
“It’s a great club, and I’ll certainly be coming down and supporting them. It’s a whole lot better than shopping with the wife on a weekend.”
Gammans owns Highbrook Holdings, which has its head office in Wakefield.
He said: “I think I need to concentrate on my business.
“I’ve been running it for 10 years, and we offer financial services, dealing with things like pensions.”
His particular highlights as Brig chairman were reaching the Lancashire Cup final at Bolton’s Reebok Stadium this season, and the play-off game against FC United last year.
He added: “I definitely didn’t leave because of the results – we finished seventh, and our youngsters won their reserve league.
“Brig have some good players and staff, they just need to bring in a few new fresh faces over the summer period to make them stronger.
“I think all clubs are going to find it tough financially, but if the club nurtures the team from last year, I think they have a great chance of finishing in a good position next season.
“The advice I would give to the new chairman is to devote a lot of time and enthusiasm into the job. It’s certainly life-consuming. The job is made much harder because whatever you say, you are always going to upset someone.
“I think it’s a bit of a demanding thing, especially when you’re travelling to Durham away on a Tuesday night, and putting all your family holidays on hold.”
The 59-year-old will now have more time on his hands and is planning a winter cruise.
However, he added: “I’m definitely looking forward to some more holidays but when I’m on them my thoughts will still be with the club.”
