Regularly, west Scottish island turning up in recount (7)
I believe the answer is:
narrate
'recount' is the definition.
('narrate' can be a synonym of 'recount')
'regularly west scottish island turning up' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'scottish island' becomes 'arran' (I've seen this before).
'turning up' shows that the letters should be reversed in order.
The alternating letters of 'west' are 'et'.
'et'+'arran'='etarran'
'etarran' written backwards gives 'NARRATE'.
'in' is the link.
(Other definitions for narrate that I've seen before include "Report; tell" , "Tell us the story" , "'Recount, tell (7)'" , "Read" , "Chronicle" .)
