GTMC chief executive Paul Wait is to leave his role this summer to become chief operating officer of Southall Travel Group.
Wait joined the GTMC in January 2013, following a high-profile career including roles at American Express and Virgin Atlantic.
Paul Allan, GTMC chairman, said: “We wish Paul huge success in his future career as COO at Southall Travel Group and will begin looking for a new chief executive of the GTMC with the organisation in an exceptionally strong place.
“Paul’s extensive efforts, innovations and phenomenal drive for success have transformed the GTMC and we now have an opportunity to continue to build on his sterling work.
“Over the last few years the GTMC has become synonymous with an entrepreneurial spirit and has enjoyed a high profile. We are in the best possible position for the GTMC to continue to grow under the direction of the accomplished board.”
Wait added: “After over four years at the GTMC I have enjoyed incredible support from the business travel community, and the opportunity to make considerable changes to the organisation.
“These evolutions now mean that the GTMC is ready to carry on to the next phase of its exciting history under new leadership. I look forward to working with a successor over the coming months.”
