Sheets in headline news (5)
I believe the answer is:
linen
'sheets' is the definition.
(I've seen this before)
'in headline news' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LINEN' is hidden within 'headline news'.
(Other definitions for linen that I've seen before include "Sheets, cloths, napkins etc" , "sheets, perhaps" , "Tablecloth material" , "Fabric, originally just spun flax" , "Spun fibres of flax" .)
