Superb puzzle imo. Mostly on the gentle side, but like others I struggled in the SW.
Got off to a flying start with most of the top half done pretty quickly. The long clues 7d, 14a, 17a held me up a while, but once they went in I was left with 18d, 20d, 24a, and 26a — these accounted for over half my solving time, although once 18d went in, the rest followed quickly.
Loads of contenders for COD, I’ll go with 1a.
Thanks to Philistine.
