Would love that quiz but would you include all the residents parties? The likes of Ashfield Independents and Aspire currently have large groups and have been around for a while, so maybe you'd say include them? But then some localist parties only have 1 or 2 seats on 1 council and may be very short-lived. Don't how anybody could possibly know them all without simply learning them for the purpose of the quiz. But maybe that doesn't matter!
Are the seats that are not taken up by Sinn Fein treated as Independent in the UK section or are they just ignored? They probably should be there somewhere.
Nominated!
A local government version would be good too, although much more work clearly...
