Ray Trew has quit his role as chairman of Notts County and put the League Two side up for sale.
The businessman, who took charge at Meadow Lane in 2010, said that he had made the decision after his family received "foul" and "mindless" abuse from some fans.
"It is with very mixed emotions that I announce the end of my tenure as Chairman of Notts County Football Club, as I put the club up for sale, having reevaluated my position in light of recent events," Trew wrote in a letter published on the club's website.
"I must start by stressing that this is not me backing away from a challenge, I do not do that and, indeed, if I'd have wanted to I would have done so some time ago because it has been a difficult journey at times. However, when my family are subjected to kind of foul, mindless abuse that they have been in recent days, both in person and courtesy of the oh so brave keyboard warriors, regardless of whether this is just the minority ruining it for the larger supporter base, I have to make changes.
"That said, whilst I have a somewhat bad taste in my mouth from the vitriol spouted by some, I do not walk away lingering on any negativity but instead will take with me the many happy memories that I have accrued from my time at Meadow Lane."
Trew's announcement comes with the club 16th in League Two following their relegation from the third tier last season.
