I'm still stuck on four, in the top left corner, and I wonder if some kind person can give me a clue to these:
1a. Feeble Bob, vulnerable type (4,4)
I have only the 1st (L) and the 7th letter (C) L?????C?
2d. US post-operative chief covers large state (7)
????M?N - this could possibly be MAILMAN but I'm not sure.
3d. Outfit showing force, ejecting Ukrainian leader (5)
????S
10a. Eton's first eleven lost - side finally cast out. (5)
E????
Thanks,
