East Ender’s pastime adopted by lean government influencer (8)
I believe the answer is:
lobbyist
'influencer' is the definition.
(someone who lobbies politicians)
'east ender's pastime adopted by lean government' is the wordplay.
I cannot quite see how this works, but
'by' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lobbyist that I've seen before include "political campaigner" , "One tries to influence government in favour of their cause" , "pusher" , "'To - it may concern'" , "figure influencing lawmakers" .)
