Help please:/
26a I got 'onset' for 'more than a walk-on part' as More than a walk=onset, from on and set-part. However, this seems to get in the way of my ideas for the intersecting answers. Am I on the right track or not?
Also with 27a, "polish tribe going round Spain (5)" I thought possibly an anagram of 'tribe' for a city in Spain, but not sure. letters I have for this are _ _E_ _.
Thanks, Rob :)
