Campbell, who has headed up the escorted touring operations for more than five years, will stay on to support a transition to a new leader. G Touring confirmed the move on Friday afternoon (2 September).
"It has been a privilege to lead the fantastic team at G Touring over more than five years," said Campbell. "I am proud to have been part of this amazing journey and all that we have achieved together.
"My focus is now to support the successful transition to a new leader through to the end of the year. G Touring is in amazing shape and I wish it every success in the future."
Bruce Poon Tip, founder and owner of G Touring, paid tribute to Campbell. "Alastair was a great leader for Travelsphere and Just You before Covid, and was outstanding during the pandemic. I cannot thank him enough for his hard work and the passion he has brought to G Touring. We wish him all the best in his future endeavours."
Poon Tip added: "As sad as we are to see him leave, leadership change presents a unique opportunity at a time when our industry is in flux and the tourism landscape is evolving."
