Daily rounds too much, having to go to North London suburb (6)
I believe the answer is:
sutton
'london suburb' is the definition.
(Sutton is a London borough)
'daily rounds too much having to go to north' is the wordplay.
'daily' becomes 'sun' (daily UK newspaper).
'rounds' means one lot of letters goes inside another.
'too much' becomes 'ott' (short for over the top).
'having to go to north' shows that the letters should be reversed in order (in a down clue, letters go up or \'north\').
'ott' written backwards gives 'tto'.
'sun' going around 'tto' is 'SUTTON'.
(Other definitions for sutton that I've seen before include "South London borough" , "town, south of London" .)
