Nominate a parking issue (7)
I believe the answer is:
appoint
'nominate' is the definition.
('appoint' can be a synonym of 'nominate')
'a parking issue' is the wordplay.
'parking' becomes 'p'.
'issue' becomes 'point'.
'a'+'p'+'point'='APPOINT'
(Other definitions for appoint that I've seen before include "Furnish" , "Assign to a post" , "Choose for a job" , "Establish" , "Name" .)
