Seeing posh car from Yorkshire, these people cause controversy (6)
I believe the answer is:
trolls
'these people cause controversy' is the definition.
(as in online trolls)
'seeing posh car from yorkshire' is the wordplay.
I cannot really see how this works, but
'car' could be 'rolls' (short for Rolls Royce) and 'rolls' is found in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trolls that I've seen before include "Mythical Scandinavian dwarfs" , "Peer Gynt dwarfs" , "Supernatural dwarfs or giants in Scandinavian myth" , "Scandinavian goblins" , "internet pests" .)
