Eccles getting help upon rejection in the papers, perhaps (5)
I believe the answer is:
media
'papers perhaps' is the definition.
(paper is a kind of medium)
'eccles getting help upon rejection' is the wordplay.
'eccles' becomes 'me' (where the crossword setter is 'Eccles').
'getting' says to put letters next to each other.
'help' becomes 'aid' (synonyms).
'upon rejection' says the letters should be written in reverse.
'aid' backwards is 'dia'.
'me'+'dia'='MEDIA'
'in the' is the link.
(Other definitions for media that I've seen before include "Agencies" , "Means of mass communication" , "Newspapers, TV, radio etc" , "sources of information" , "reporting channels" .)
