Would anyone be willing to give me a nudge on 20a and 45a?
My grid is otherwise full, although I'm not quite sure I can parse 4d so perhaps this is giving me a second letter in 20a that then doesn't seem to create any word in Chambers.
In 45, I have letters 1,3,5,6 and can make a word from the clue but not one that would be the last two words of the clue. Im guessing a letter comes out, maybe? But perhaps, I've made a mistake elsewhere.
Also, I haven't found an abbreviation! Unless it's 10 down?
Thanks.
