One in charge of newspaper is in hospital (9)
I believe the answer is:
organiser
'one in charge' is the definition.
(I've seen this before)
'newspaper is in hospital' is the wordplay.
'newspaper' becomes 'organ' (I've seen this before).
'in hospital' becomes 'er' (I've seen this in other clues).
'organ'+'is'+'er'='ORGANISER'
'of' is the link.
(Other definitions for organiser that I've seen before include "Manager" , "Runner" , "One in charge" , "impresario" , "One making arrangements" .)
