A politician hugged by a baby? (6)
I believe the answer is:
pamper
'baby?' is the definition.
('pamper' can be a synonym of 'baby')
'a politician hugged by a' is the wordplay.
'politician' becomes 'MP' (Member of Parliament).
'hugged by' is an insertion indicator (I've seen this in other clues).
'a' becomes 'per' (eg 'one a day' means 'one per day').
'a'+'mp'='amp'
'amp' placed into 'per' is 'PAMPER'.
(Other definitions for pamper that I've seen before include "baby" , "Mollycoddle" , "Treat luxuriously" , "'Indulge, spoil (6)'" , "Overindulge (someone)" .)
