It's said in France to be the same (5)
I believe the answer is:
ditto
'be the same' is the definition.
(ditto means the same as previously mentioned)
'it's said in france to' is the wordplay.
'it's said in france' becomes 'dit' ('said' in French).
'dit'+'to'='DITTO'
(Other definitions for ditto that I've seen before include "Repeat (instruction)" , "In lists, the same again with two small marks" , "Mark used to indicate repetition" , "Copy" , "Two dots indicating the same again" .)
