Procession of cars round Democrat on the move? (9)
I believe the answer is:
motorcade
'procession of cars' is the definition.
(I've seen this in another clue)
'round democrat on the move?' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'on the move?' indicates anagramming the letters (I've seen 'on the move' mean this).
'o'+'democrat'='odemocrat'
'odemocrat' is an anagram of 'MOTORCADE'.
(Other definitions for motorcade that I've seen before include "Maybe Kennedy's entourage" , "vehicles in procession" , "Convoy" , "vehicular procession" , "Vehicle procession" .)
