Got to this late in the day and can never do these later than I should. Was wondering about:
23a - study source behind revolutionary scrap (7)
E?A?I?E Examine????
6d - parts of poem about a ruinous palace (10). versailles?
26a - unaware, I admit, about drama (8) ignorant?
10 d - signal at end of race varied following delay. (9,4). Chequered flag??
Thanks!
