Still stuck on a few. 32A Stick at protecting peace project: ?S?P?A??. 23d A barrel with chlorine for city in Greece or Bulgaria, say: G?E?? ?N?L? And 54a One angry if out to lunch with nothing to eat: E?O? R?N?Y And, while I'm on, for 7d I presume the answer is "pedro", but can't see why. Any help greatly appreciated: got to start the next one tomorrow!
