Card player with dodgy relations in part of England (4,6)
I believe the answer is:
east sussex
'part of england' is the definition.
(I know that East Sussex is part of England)
'card player with dodgy relations' is the wordplay.
'card player' becomes 'east' (bridge players are known by compass position).
'with' says to put letters next to each other.
'dodgy' becomes 'sus' (suspicious).
'relations' becomes 'sex' (euphemism for sex).
'east'+'sus'+'sex'='EAST SUSSEX'
'in' is the link.
(Other definitions for east sussex that I've seen before include "English Channel county" , "area that's down a lot" .)
