Concern there's pressure guaranteed when leader gone (7)
I believe the answer is:
pertain
'concern' is the definition.
(I know that concern can be written as pertain)
'there's pressure guaranteed when leader gone' is the wordplay.
I cannot quite see how this works, but
'there's' could be 'n' (I've seen this in other clues) and 'n' is found in the answer.
'pressure' could be 'p' (abbreviation) and 'p' is found in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pertain that I've seen before include "Have relevance" , "Painter inclined to be relevant" , "Painter (anag) - relate (to)" , "Be related or applicable (to something)" , "Be relevant, or belong as part" .)
