I was looking back at an old Listener crossword and saw this clue which I still can't totally work out the wordplay for....
Maybe propose for a prize minister before entering Number 10 shortly (8) NOMINATE
I did think 'Number 10 shortly' was NO TE(n) around MIN(ister), but that leaves an 'A' for 'before' - can anyone put me out of my misery:-)
