Duffy guided Brechin to the First Division play-offs, where they lost to Cowdenbeath
Jim Duffy has resigned as manager of Brechin City after 17 months in charge of the Division Two club.
The former Hibernian and Dundee manager replaced Michael O'Neill in January 2009 and guided the club to the First Division play-offs this season.
Brechin lost 3-0 on aggregate to Cowdenbeath in the final.
Duffy told BBC Scotland: "I felt, if I made the decision now, it would let Brechin get a new manager in, which is important for their future."
Brechin City secretary Ken Ferguson told BBC Scotland the club hopes to appoint a new manager quickly following Duffy's departure.
We have a handful of applications in already and we are keen to get somebody in place quickly

"We plan to be active about things - we don't intend to take too long about it," said Ferguson.
"We have a handful of applications in already and we are keen to get somebody in place quickly."
Among the early front runners for the job are two former Dundee United midfielders.
Dave Bowman, now a community coach at Tannadice, and Ray McKinnon, manager of Junior side Lochee United, are both contenders for the position.
Duffy, who was director of football with Hearts in 2006 and had coaching spells with Chelsea, Portsmouth and Norwich, insisted he had parted on amicable terms and was not seeking an immediate return to coaching.
"It's something I've thought about for the last couple of months," said Duffy.
"I just wanted to get to the end of the season and give everything we had to try and achieve promotion.
"Unfortunately, we fell at the final hurdle.
I felt it was the right time for myself to try and move on. I don't have anything up my sleeve, but I just felt I had given the part-time situation a go for a couple of seasons and it was a great education for me
"I felt it was the right time for myself to try and move on. I don't have anything up my sleeve, but I just felt I had given the part-time situation a go for a couple of seasons and it was a great education for me.
"The club were terrific and the chairman was excellent. I have a good relationship with everyone at the club."
Duffy insisted he would be interested in taking on a more permanent, full-time role at some point in the future but denied he was interested in the vacant managerial position at Morton, or in a return to manage in the Scottish Premier League.
"I haven't applied for any jobs or used contacts to apply for any jobs," said Duffy.
"I've just left Brechin and I have some family issues to deal with over the coming days and months.
"Once those are finished, hopefully, there will be a brighter time around the corner."
