Tone changed around capital in Libya after first of sanctions lifted (6)
I believe the answer is:
stolen
'lifted' is the definition.
(I've seen this in another clue)
'tone changed around capital in libya after first of sanctions' is the wordplay.
'changed' indicates an anagram.
'around' means one lot of letters goes inside another.
'capital in' says to take the initial letters.
'after' is a charade indicator (letters next to each other).
'first of sanctions' becomes 's' (1st letter of 'sanctions').
The first letter of 'libya' is 'l'.
'tone' is an anagram of 'toen'.
'toen' placed around 'l' is 'tolen'.
'tolen' after 's' is 'STOLEN'.
(Other definitions for stolen that I've seen before include "Illegally taken" , "Taken by thieves" , "Nicked" , "Purloined or embezzled" , "without keeping to left" .)
