Free travel i.e. around Belgium? It's true (9)
I believe the answer is:
veritable
'true' is the definition.
(thesaurus)
'free travel i e around belgium?' is the wordplay.
'free' is an anagram indicator.
'around' means one lot of letters goes inside another.
'belgium?' becomes 'b' (international vehicle registration code).
'travel'+'i'+'e'='travelie'
'travelie' is an anagram of 'veritale'.
'veritale' placed around 'b' is 'VERITABLE'.
'it's' is the link.
(Other definitions for veritable that I've seen before include "Positive" , "Actual -- authentic" , "True, genuine" , "True - real" .)
