Here perhaps needle, always the way to interrupt journalist (8)
I believe the answer is:
haystack
'here perhaps needle' is the definition.
(as in finding a needle in a haystack)
'always the way to interrupt journalist' is the wordplay.
'always' becomes 'ay' (archaic term for 'always').
'the way' becomes 'st' (abbreviation for street).
'to interrupt' indicates putting letters inside.
'journalist' becomes 'hack' (hack can informally mean a journalist).
'ay'+'st'='ayst'
'ayst' inserted inside 'hack' is 'HAYSTACK'.
(Other definitions for haystack that I've seen before include "Large pile of fodder" , "Large mound of dried grass" , "Pile of cut grass" , "Rick of dried grass" , "Pile of dried grass" .)
