I'm stuck on the last one: 21d. Asian at last in a state turning up here (6). I have ?I?N?A. So the solution must be VIENNA (VA round N and IEN reversed) but I've not been able to find anywhere called Nei other than that Google tells me that it can mean Inner as in Inner Mongolia, but that does seem far fetched. I may well be clutching at straws when there's a life belt within reach. i'd be grateful for any helpful thoughts.
