International law not broken (6)
I believe the answer is:
intact
'not broken' is the definition.
(I've seen this before)
'international law' is the wordplay.
'international' becomes 'int' (abbreviation for international).
'law' becomes 'act' (I've seen this in another clue).
'int'+'act'='INTACT'
(Other definitions for intact that I've seen before include "Inviolate" , "Entire, untouched" , "Undamaged, not broken" , "Flawless" , "Unbroken - sound" .)
