4016: Motion by Samuel


This was a nicely themed puzzle from Samuel. The letters which moved spelled AYES TO THE RIGHT, NOES TO THE LEFT. This explained how to enter the ten thematic answers, e.g.CANOPY was entered NOCAPY and VILAYETS as VILTSAYE. The title was explained as a motion in the Houses of Commons. 5dn was DIVISION LOBBY and 19ac, which resolved the issue was THE NOES HAVE IT.

Where letters have moved a corrected version is shown in parentheses with the moved letter in upper case.
