Countryside Alliance (CA) chairman Kate Hoey is to stand down after nine years.
The Labour MP for Vauxhall said she was “sad” to be resigning.
“The organisation has achieved much in the past nine years, but I will always be most proud that having joined when hunting faced such uncertainty, I leave with new generations queuing up to join the hunting field,” she said.
Her successor is to be discussed at the next board meeting.
Deputy chairman Lord Mancroft added: “Kate’s contribution is immeasurable. Her determination stiffened us all for the fight and there is no way that hunting would have weathered the storm as successfully as it has if it had not been for her.”
