Harry girl admitting paper's misleading remark (4-5)
I believe the answer is:
half-truth
'misleading remark' is the definition.
'harry girl admitting paper's' is the wordplay.
'harry' becomes 'hal' (Hal can be a nickname for Harry or Henry).
'girl' becomes 'ruth' (girl's name**).
'admitting' is an insertion indicator.
'paper' becomes 'ft' (newspaper the FT, Financial Times).
'hal'+'ruth'='halruth'
'halruth' enclosing 'ft' is 'HALF-TRUTH'.
(Other definitions for half-truth that I've seen before include "Mild deception" , "Statement intended to mislead" , "Statement conveying only part of the situation - 50% retained" , "Statement that is only 50% accurate" .)
