Iraqi Airways' chief executive, Kifah Hassan Jabbar, has been freed to return to Iraq after a travel ban was lifted.
His travel documents had been seized under a Kuwaiti-driven legal ambush shortly after the first Iraqi Airways flight in years arrived at London Gatwick on 25 April.
But the Iraqi transport ministry says that UK court authorities have returned Jabbar's documents, adding that he is free to travel back to Baghdad. It describes the Kuwaiti actions as "unbecoming behaviour".
Kuwait Airways and Iraqi Airways have been locked in a long-running court dispute over reparations following the Gulf conflict in 1990-91. Kuwait Airways considers the Iraqi Airways aircraft fleet an asset liable to seizure.
