 However, no distinctive flag was created for Akrotiri and Dhekelia and no grant of arms by the College of Arms on which to base a Blue Ensign-type flag common to most British Overseas Territories.As a result, the Union Jack became the flag of Akrotiri and Dhekelia by default.The Union Jack is flown over all official buildings in Akrotiri and Dhekelia as well as at border checkpoints.
