Politician in India two journalists obstructed (7)
I believe the answer is:
impeded
'obstructed' is the definition.
('impede' can be a synonym of 'obstruct')
'politician in india two journalists' is the wordplay.
'two journalists' means two substitutions for 'journalist'.
'politician' becomes 'MP' (Member of Parliament).
'in' is an insertion indicator.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'journalist' becomes 'ed' (short for editor).
'journalist' becomes 'ed' (short for editor).
'i'+'ed'='ied'
'mp' put into 'ied' is 'imped'.
'imped'+'ed'='IMPEDED'
(Other definitions for impeded that I've seen before include "Hampered" , "Got in the way of" , "Held up" , "Hindered, slowed down" , "Blocked (progress)" .)
