More than confident about New England station introducing EastEnders, the British version (8)
I believe the answer is:
cockneys
'station introducing eastenders the british version' is the definition.
I can't tell whether this defines the answer.
'more than confident about new england' is the wordplay.
I cannot quite see how this works, but
'about' could be 'c' (abbreviation for 'circa') and 'c' is found in the answer.
'new' could be 'n' and 'n' is found in the answer.
'england' could be 'e' and 'e' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cockneys that I've seen before include "Natives of London's East End" , "London's traditional Eastenders" , "East Londoners" , "Native London eastenders" , "Natives of the east end of London" .)
