All the way from Brighton (5)
I believe the answer is:
right
'all the way' is the definition.
(synonyms)
'from brighton' is the wordplay.
'from' indicates the answer is hidden within the clue.
'RIGHT' is hidden in the letters of 'brighton'.
(Other definitions for right that I've seen before include "A person is entitled to it" , "Correct; political wing" , "Not left" , "Correct; entitlement" , "Correct - starboard" .)
