Been watching the forum to see if my two problem clues have been solved. But, no ....! They are 20a "Publisher is litigious type", and I've got I?S?E?R. Issuer ? Certainly publishes things, but where's the litigious bit - issuing summonses perhaps? All seems a bit weak to me. And then 47a "capital story about origin of war on for ages". My letters are L?L?N?W? I think I've got all the down answers right. Any help gratefully received.
