Look to Italy to welcome France (6)
I believe the answer is:
Here is my best explanation:
'look' is the definition.
(a quick or furtive look)
'to italy to welcome france' is the wordplay.
'to' becomes 'shut' (I've seen this before).
'italy' becomes 'i'.
'to welcome' is an insertion indicator (in sense of 'inviting in').
'france' becomes 'f'.
'shuti' enclosing 'f' is 'SHUFTI'.
