Independent politician learning to ask (7)
I believe the answer is:
implore
'ask' is the definition.
(thesaurus)
'independent politician learning' is the wordplay.
'independent' becomes 'i'.
'politician' becomes 'MP' (Member of Parliament).
'learning' becomes 'lore' (both can mean tradition or knowledge).
'i'+'mp'+'lore'='IMPLORE'
'to' is the link.
(Other definitions for implore that I've seen before include "Beg desperately" , "Ask earnestly" , "Beg earnestly, beseech" , "More lip (anag)" , "Beg earnestly, plead" .)
