Times Cryptic No 28284 – Saturday, 7 May 2022. Solved to the sounds of Haydn?

I’d never heard of the political arrangement at 12D, so no music played for me … tho’ I’m sure it was different for some. Anyhow, the answer was clear from the helpers. Nor was my geography up to naming the answer to 2D – that one I had to look up. Everything else was within my ken. Thanks to the setter for a very enjoyable puzzle. How did you all get on?
