The new structure consists of an elected executive board responsible for strategic planning and overall direction of the association, with a chairman, chairman elect, chief executive, treasurer, sales and marketing director, and secretary.
The board will hold monthly meetings and be supported by an industry council, elected by the membership and made up of industry representatives from sectors such as hotels, convention centres and industry suppliers.
The changes were announced at the MIA's annual general meeting in London yesterday.
MIA chairman Peter Darnell said: "As we experience membership growth, with new members joining us from a wide variety of industry sectors, this restructure extends the reach of the association, providing a structure for broader representation. With more board members, each industry sector will be better represented and with council members providing sector intelligence, we can further improve the response to members' needs."
