Conservative charity almost collected (4)
I believe the answer is:
calm
'collected' is the definition.
(thesaurus)
'conservative charity almost' is the wordplay.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'charity' becomes 'alms' (alms is a kind of charity).
'almost' means to remove the last letter (most of the word but not all of it).
'alms' with its final letter removed is 'alm'.
'c'+'alm'='CALM'
(Other definitions for calm that I've seen before include "Imperturbable, soothe" , "Cool and collected" , "Absence of wind" , "Peaceful, tranquil" , "Placid, unexcited" .)
