Nick Bunting has left his role as chief executive of the Motor Sports Association after little more than six months in the job.
The MSA said on Thursday that Bunting, who switched from a similar role with the Rugby Football Union in May, had left by mutual consent.
“I have very much enjoyed working with the MSA staff and all the dedicated volunteers and organisations within the sport,” said Bunting.
“It has been an interesting challenge to understand the motor sport environment and I am grateful for the support that has been given to me from all quarters.
“I am delighted that we have been able to effect some changes that will enable the sport and the organisation to move forward and I wish the MSA and everyone connected with British motor sport every success in the future.”
In Bunting’s absence, MSA general secretary Rob Jones has been appointed as its acting CEO.
MSA chairman Alan Gow praised the job done by Bunting during his tenure as chief executive.
“Nick was recruited to undertake a specific transitional role to prepare the MSA for future transformation,” said Gow.
“He has undertaken an internal restructure of the staff and functional departments, implemented a new IT system, reviewed our business structures and begun the establishment of a customer-focused culture.
“Nick has also reviewed the strategic opportunities for the MSA’s future in such areas as participant development, championship structures, regulations and marketing and communications.
“During his tenure he has successfully laid out the pathway for this transition and identified that a specific style of leadership is required to achieve this.
“Therefore, by mutual consent, he has decided not to take up the possibility of the continued role as MSA chief executive.”
