Is 18d NIDUS or NIDAL please?
38 looks like YELTSIN, but can’t see why! But I don’t have the crosser yet, 27d, Ambassador axes core group of bolshy radicals (6). Any help, thanks. Also a nudge on 5a welcome.
Hi Lumen
It's NIDAL (after SALADIN with A extra letter).
38 is YELT, like 'slip', another name for a young pig
For27d, think maths. for the 'axes' and combine with core of 'bolshy'
