Authoritarian government gets émigré travelling (6)
I believe the answer is:
regime
'authoritarian government' is the definition.
(I've seen this before)
'emigre travelling' is the wordplay.
'travelling' indicates anagramming the letters.
'emigre' anagrammed gives 'REGIME'.
'gets' is the link.
(Other definitions for regime that I've seen before include "Method or system of government" , "Routine" , "Command" , "Government, especially an authoritarian one" , "co-ordinated programme" .)
