Bright around north-east for Mrs Mop? (7)
I believe the answer is:
cleaner
'mrs mop?' is the definition.
(1940s British radio character)
'bright around north-east' is the wordplay.
'bright' becomes 'clear' (I've seen this before).
'around' indicates putting letters inside.
'north east' becomes 'ne'.
'clear' placed around 'ne' is 'CLEANER'.
'for' is the link.
(Other definitions for cleaner that I've seen before include "less sleazy?" , "More hygienic" , "Char; detergent" , "Eg, launderer, duster" , "Daily help" .)
