Ex-communist card player fed without hesitation (4,6)
I believe the answer is:
east german
'ex-communist' is the definition.
(East Germany was a former communist country)
'card player fed without hesitation' is the wordplay.
'card player' becomes 'east' (bridge players are known by compass position**).
'fed' becomes 'gman' (both are slang for US federal agents).
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'hesitation' becomes 'er'.
'gman' going around 'er' is 'german'.
'east'+'german'='EAST GERMAN'
(Another definition for east german that I've seen is " inhabitant of former country".)
