Leader to check over refuge on way up (9)
I believe the answer is:
editorial
'leader' is the definition.
(type of newspaper article)
'check over refuge on way up' is the wordplay.
'check' becomes 'edit' (edit can mean to check or emend).
'over' becomes 'o' (cricket abbreviation).
'refuge' becomes 'lair' (I've seen this in another clue).
'on way up' says the letters should be written backwards.
'lair' reversed gives 'rial'.
'edit'+'o'+'rial'='EDITORIAL'
'to' acts as a link.
(Other definitions for editorial that I've seen before include "Statement of a newspaper's opinion" , "considered view on paper" , "matter of opinion" , "Article giving opinion of a newspaper" , "paper item" .)
