Providing a fix in political aide merely given a lift (8)
I believe the answer is:
remedial
'providing a fix' is the definition.
(something offering a remedy)
'in political aide merely given a lift' is the wordplay.
'in' indicates a hidden word.
'given a lift' says the letters should be written backwards.
'laidemer' can be found hidden inside 'political aide merely'.
'laidemer' back-to-front is 'REMEDIAL'.
(Other definitions for remedial that I've seen before include "for the lower classes" , "Intended to put right" , "Designed to be therapeutic" , "intended to correct something" , "'Therapeutic, healing (8)'" .)
