Whistle-blower with no right to encourage Eastern asylum seeker (7)
I believe the answer is:
refugee
'asylum seeker' is the definition.
(I've seen this before)
'whistle-blower with no right to encourage eastern' is the wordplay.
'whistle blower' becomes 'ref' (I've seen this in other clues).
'with no' indicates named letters should be taken away.
'right' becomes 'r' (common abbreviation).
'to encourage' becomes 'urge' (I've seen this before).
'eastern' becomes 'e'.
'urge' with 'r' taken out is 'uge'.
'ref'+'uge'+'e'='REFUGEE'
(Other definitions for refugee that I've seen before include "One fleeing troubles" , "Asylum seeker" , "One who seeks asylum abroad" , "one seeking shelter" , "One fleeing homeland" .)
