He said: “The last 17 years have represented an incredible journey with many amazing experiences along the way. To help build Hills Balfour to the market leading position it enjoys today, along with growing the best team in the business with a client list to match, has been a pleasure to be a part of.”

He will stay in his post until the end of August and remain a shareholder.

Sloan told TTG he would be subject to six months ‘gardening leave’ before starting a new job: “I will be staying in the industry for sure,” he said.
