We want to see as many Middlesex county flags flying, running up to, and on July 23rd!
Use the hashtag #CountyFlagsDay on your photo on Twitter, Facebook or Instagram. Alternatively you can email us your picture to countyflagsday@abcounties.com.
For the history and background of the Middlesex county flag, please see the Middlesex Flag section on the British County Flags Blog.
Colour in Middlesex!
