Transport moved along carrying party (7)
I believe the answer is:
gondola
'transport' is the definition.
(gondola is a kind of transport)
'moved along carrying party' is the wordplay.
'moved' indicates an anagram.
'carrying' indicates putting letters inside.
'party' becomes 'do' (do is a kind of party).
'along' with letters rearranged gives 'gonla'.
'gonla' placed around 'do' is 'GONDOLA'.
(Other definitions for gondola that I've seen before include "Supermarket display unit" , "Venetian boat - airship cabin" , "Traditional boat of Venice" , "Palmieris' craft" , "Craft for Venetian canals" .)
