Wheeling along, posh cars with monarch round centre of Bath (6-7)
I believe the answer is:
roller-skating
'centre of bath' is the definition.
The definition suggests a verb in its base form which matches the answer.
'wheeling along posh cars with monarch' is the wordplay.
I cannot really see how this works, but
'cars' could be 'rollers' (I have seen 'expensive cars' mean 'rollers' so perhaps 'cars' could also mean 'rollers') and 'rollers' is present in the answer.
'monarch' could be 'k' (abbreviation for king in chess) and 'k' is located in the answer.
This explanation may well be incorrect...
'round' is the link.
Can you help me to learn more?
(Other definitions for roller-skating that I've seen before include "Using wheeled boots" , "sport on wheels" , "Running on wheeled boots" .)
