British ready for some loud shows of affection? (8)
I believe the answer is:
smackers
I believe this clue is a double definition.
'british ready' is the first definition.
(smacker can mean a British pound, ie some 'ready')
'some loud shows of affection?' is the second definition.
'for' is the link.
(Other definitions for smackers that I've seen before include "big kisses" , "money" , "worth more than one pound" , "Parents enforcing discipline perhaps" , "People striking" .)
