1a Looking for scraps? (11) ???L?G?RING
15A Returns and surrenders (6) ?I?L?S
18a Put in again (2-5) RE-E???T
2d Don't let people see there's something wrong (5) ??A?E
19d A park for the lesser-known actor (5) ??T?A
Thanks all - Extra could be right for 19d - bit part actor but don't know where Park fits then..?
re 18a - the second E comes from usEless (clue: to economise is of no avail = use
less) and the T at the end comes from sTymie (clue: I set my allotment to hinder golfers = anag of I set my)
Happy to be wrong on what I have already, if you can suggest better! If EXTRA is right then I have REE?E?T now.
