Love token hides rejection (4)

I believe the answer is:

veto

'rejection' is the definition.
(veto is a kind of rejection)

'love token hides' is the wordplay.
'hides' says the answer is hidden in the clue.
'VETO' can be found hidden inside 'love token'.

(Other definitions for veto that I've seen before include "bar" , "Refuse permission" , "Formally forbid" , "Right to reject a proposed measure" , "Rule out" .)

I've seen this clue in The Daily Express.
