Swede's routine win accepted by driving club (8)
I believe the answer is:
rutabaga
'swede's' is the definition.
('rutabaga' can be a synonym of 'swede')
'routine win accepted by driving club' is the wordplay.
I cannot really see how this works, but
'routine' could be 'rut' (rut is a kind of routine) and 'rut' is found in the answer.
'accepted' could be 'a' (financial abbreviation) and 'a' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rutabaga that I've seen before include "US term for swede" , "Swede; tuba raga (anag.)" , "vegetable in America" , "American term for swede" .)
