Final two clues, I have solutions for both but, being more interested in the purity than the prize (not intended to be an entry for Pseud's Corner, however appropriate) I value your opinion.
29d: Nonconformist Party: overthrown, finished and no longer in power (3,3,3)
??d ?n? o?t
odd one out looks good which gives me letter no 5 of:
28a: Sent stuff in this to beat opponent on points (6)
o?t?o?
outbox looks good.
Neither is as definitive as I would like it to be, but what do youse guys think - is there a better solution of either or both? Thanks, JohnT
