Decisions such as personnel changes are often announced late, if at all. Awaidha Murshed al-Marar was appointed the new chairman of Abu Dhabi Airports, and some board members have also been replaced, a company spokeswoman told Reuters. Mr Marar is already chairman of Abu Dhabi's Department of Municipal Affairs and chairman of Etihad Rail. Mohamed Khalifa al-Mubarak is the new chairman of TDIC, a company source confirmed. Mr Mubarak's existing roles include chairman of Abu Dhabi Tourism & Culture Authority and the chief executive of Aldar Properties. There was no formal announcement of the new appointments by the firms. However, websites of both entities showed the changes on Sunday. "The new chairmen already hold the top positions in related entities in the transport and tourism sectors respectively, so it makes sense to bring (Abu Dhabi Airports) and TDIC under them," a source familiar with the matter told Reuters on condition of anonymity.
