I sometimes worry I've got into a bit of a rut with this podcast, chatting away about housing and public transport with people who largely agree with me. So this week, to mix things up a bit, I decided to have a fight.

Henry Hill is the assistant editor at Conservative Home (booooooooooo). There, he writes a lot about politisc of the devolved nations of Scotland and Wales – despite his belief that the late '90s devolution settlement that created the Scottish Parliament and Welsh Assembly was a historic mistake (hissssssssssssssssssssss).

So: what is Henry's argument? Doesn't a nation have the right to self-government? Hasn't the centralised British state been a disaster for much of the United Kingdom? And what about the parallels with Brexit? All these and more questions will be, if not answered, then at the very least discussed.

Skylines is the podcast from the New Statesman’s cities site, CityMetric. It’s hosted by Jonn Elledge.
