Her Majesty's Government has instructed that to mark Armed Forces Week, Government buildings should fly the Armed Forces Flag from 08:00 on Monday 20 June until 20:00 on Saturday 25 June 2016.
Departmental buildings in London with more than one flagpole are also to fly the Rainbow Flag during this period to celebrate Pride Week. Where there is only one flagpole the Armed Forces Flag will in most cases take precedence.
Please note that 21 June 2016 is a designated flag-flying day. If there is only one flagpole, the Union Flag should be flown. If there are two, the Union Flag should be flown on the senior pole.
Local authorities are not bound by these instructions but may wish to follow them for guidance. Devolved administrations are responsible for issuing instructions for the flying of the Union Flag on buildings in their estate and others as necessary.
For information about Armed Forces Day flags and issues relating to the flying of flags more generally, please contact the Officer in Waiting at the College of Arms.
