British plead to sunbathe (4)
I believe the answer is:
bask
'sunbathe' is the definition.
(I've seen this in another clue)
'british plead' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'plead' becomes 'ask' (I've seen this in another clue).
'b'+'ask'='BASK'
'to' acts as a link.
(Other definitions for bask that I've seen before include "Lie in the sun" , "revel" , "Lie in warmth" , "Lie in sunshine" , "Sun oneself (like a kind of shark?)" .)
