Cancel instruction to empty basin (4,3,4)
I believe the answer is:
pull the plug
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for pull the plug that I've seen before include "Scrap" , "Stop (something) continuing - empty the bath!" .)
I've seen this clue in The Times.
Want a hint initially instead of a full solution?
