Maddest lie about part of the world (6,4)

I believe the answer is:

middle east

'part of the world' is the definition.
(the Middle East is a region of the world)

'maddest lie about' is the wordplay.
'about' indicates an anagram.
'maddest'+'lie'='maddestlie'
'maddestlie' anagrammed gives 'MIDDLE-EAST'.

(Another definition for middle east that I've seen is " Troubled zone".)

I've seen this clue in The Daily Express.
