4d "Like (in dealings with the far right) the Republican party's conservative evil soul, perhaps" (9)
?O?L?S?V? Looks like it must be COLLUSIVE (anagram of evil soul and c for conservative) but if so can't see where dealing with the far right comes in.
15d "Unhealthy agenda - Labour ends in folly" (10)
??S?N?T?R? looks like INSANITARY for unhealthy but if so can't see how Labour and agenda fit
Any help much appreciated
