Upset setter needs support and hug (7)
I believe the answer is:
embrace
'hug' is the definition.
(to embrace someone is to hug them)
'upset setter needs support' is the wordplay.
'upset' is a reversal indicator.
'setter' becomes 'me' (the setter of the clue).
'needs' is a charade indicator (letters next to each other).
'support' becomes 'brace' (bracing is a kind of supporting).
'me' written backwards gives 'em'.
'em'+'brace'='EMBRACE'
'and' is the link.
(Other definitions for embrace that I've seen before include "Include, contain" , "Hold closely, include" , "Hug or accept eagerly" , "Take in arms" , "squeeze" .)
