I've read news about many British communities designing local flags in celebration to the 750th anniversary of the first Parliament, called by Simon de Montfort in 1265. I thought "Why not a flag for Parliament?".
This post is inspired by Sammy McKittrick's ideas here and here.
My idea for a flag for the British Parliament is the following:
In the center of the flag, the logo of the Palace of Westminster (headquarters of Parliament), constituted by a portcullis and a crown. Red is the color of House of Lords, while green represents House of Commons.
A variation of this design is the following:
One of these flags could fly, for instance, when Parliament is on session.
Comments and suggestions are welcome.
