Hungrier English politician has row (7)
I believe the answer is:
emptier
'hungrier' is the definition.
('empty' can be similar in meaning to 'hungry')
'english politician has row' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'politician' becomes 'MP' (Member of Parliament).
'has' says to put letters next to each other.
'row' becomes 'tier' (a tier is a row of things).
'e'+'mp'+'tier'='EMPTIER'
(Other definitions for emptier that I've seen before include "I'm Peter (anag)" , "More vacuous" , "Being more hungry" , "Containing less" , "more in need of food" .)
