Sucking up on the dance floor perhaps, all backing Mercury touring Ulster with Father Ring leading the orchestra (9)
I believe the answer is:
hoovering
'sucking up' is the definition.
(I've seen this before)
'on the dance floor perhaps all backing mercury touring ulster with father ring leading the orchestra' is the wordplay.
I cannot quite see how this works, but
'on' could be 'over' (I've seen this in other clues) and 'over' is located in the answer.
'ring' could be 'o' (letter resembling a ring) and 'o' is present in the answer.
'leading' could be 'in' (in government) and 'in' is found in the answer.
'mercury' could be 'hg' (Hg is the chemical symbol for mercury) and 'hg' is present in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hoovering that I've seen before include "Domestic chore" , "sucking up" .)
