Newspaper most unlikely to charge for each column (8)
I believe the answer is:
pilaster
'column' is the definition.
(pilaster is a kind of column)
'newspaper most unlikely to charge for each' is the wordplay.
'newspaper' becomes 'i' (the i is a British newspaper).
'most unlikely' becomes 'last' (I've seen this before).
'to charge' indicates putting letters inside (charge can mean to fill).
'for each' becomes 'per' (per person).
'i'+'last'='ilast'
'ilast' going inside 'per' is 'PILASTER'.
(Other definitions for pilaster that I've seen before include "Square column" , "Rectangular column projected from wall" , "Decorative column standing out from the fa?ade of a building" , "Piles tar into a form of column" , "Rectangular column support projecting slightly from a wall" .)
