Concerning MP’s recall (8)
I believe the answer is:
remember
'recall' is the definition.
('remember' can be a synonym of 'recall')
'concerning mp's' is the wordplay.
'concerning' becomes 're'.
'mp' becomes 'member' (I've seen this before).
're'+'member'='REMEMBER'
(Other definitions for remember that I've seen before include "Summon back to mind" , "Mark" , "Keep in mind" , "Bear in mind" , "Call to mind" .)
