I've finished the crossword but have had difficulty parsing some clues. Can anyone parse the following please:
31 down, 6,5: Middle-of-the-road leader on the right dismissed hawk.
Answer: MORTAR BOARD
51 down, 3: Cheer swift runner coming up - not quite to the echo.
Answer: RAH
Where does the swift runner come into it?
Thanks in advance to all you clever people out there!
