Politician supporting unnamed writers in spooky tale (5,5)
I believe the answer is:
ghost story
'spooky tale' is the definition.
(spooky tale or story)
'politician supporting unnamed writers' is the wordplay.
'politician' becomes 'tory' (term for a Conservative Party politician).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'unnamed writers' becomes 'ghosts' (ghost writers).
'tory' after 'ghosts' is 'GHOST-STORY'.
'in' is the link.
(Other definitions for ghost story that I've seen before include "Frightful relation" , ". . . one such [SCARY TALE]" , "One giving creeps" .)
