Mechanic from EU country reportedly given a thousand in cash (6,6)
I believe the answer is:
grease monkey
'mechanic' is the definition.
(grease monkey can informally mean a mechanic)
'eu country reportedly given a thousand in cash' is the wordplay.
'eu country' becomes 'Greece' (member of the European Union).
'reportedly' shows a homophone (sound like).
'given' is a charade indicator (letters next to each other).
'a thousand in cash' becomes 'monkey' (slang term for a thousand pounds).
'greece' sounds like 'grease'.
'grease'+'monkey'='GREASE MONKEY'
'from' acts as a link.
(Another definition for grease monkey that I've seen is " Car mechanic (informal)".)
