Chef Michael Wignall is to leave Gidleigh Park, the Devon hotel where he won two Michelin stars, after just two years.
Wignall is expected to set up his own venture.
The respected chef joined Andrew Brownsword Hotels' Gidleigh Park in January 2016 from the Latymer at Pennyhill Park in Surrey, where he also held two Michelin stars.
He was awarded two Michelin stars just nine months after his move to Gidleigh Park.
Wignall said: "It's been a pleasure to live and work in Devon, and I am so proud of what I've achieved, together with my amazing team at Gidleigh Park. I'm now looking forward to my next venture which I will be announcing in the very near future".
Stephanie Hocking, CEO Andrew Brownsword Hotels said: "Michael has brought a breath of fresh air to Gidleigh Park, and his cooking, innovation and style won Michelin and industry recognition incredibly quickly. We would like to thank Michael for all his efforts that have driven the dining experience forward and have maintained Gidleigh Park's reputation as one of the UK's finest country house hotels in the UK."
