Finding this one harder than last week's two.
Not after answers (yet) but can anyone explain:
54a Courses, involving last of immigrant community welcomed by government politicians
I have: TRAJECTORIES I get the tories bit, but the rest?
41d Extend from forty to eighty days, as fragrant. I have REDOLENT but really don't know why.
25d Expose society girl, topless delinquent. I have DEBUNK and am trying to think of a word ending in UNK which means a delinquent?
