Looking for new diagrams? There is a whole new series from May 2019 onwards here!

Diagrams as featured by The New York Times!

I have tried to make sense of Brexit through a series of flow diagrams that have evolved as Brexit decisions have been taken. This blog post gathers those diagrams together, the newest versions first. In each case click the image to see the full resolution version.

All diagrams are made with draw.io. If you want to use these files for your own purposes, feel free – everything is Creative Commons Sharealike licensed. Dutch news site did precisely that here!

There are two sets of diagrams – the ones around the 29th January vote on amendments to Theresa May’s Brexit plan are at the top of this post (high res versions, draw.io XML files, and probability calculations in .ods files can be found here), and the earlier ones relating to the Meaningful Vote below (high res versions and draw.io XML files of those can can be found here).
