Thought of politician sitting in grass (10)
I believe the answer is:
remembered
'thought of' is the definition.
('remember' can be a synonym of 'think of')
'politician sitting in grass' is the wordplay.
'politician' becomes 'member'.
'sitting in' indicates putting letters inside.
'grass' becomes 'reed' (I've seen this before).
'member' inserted inside 'reed' is 'REMEMBERED'.
(Other definitions for remembered that I've seen before include "not overlooked" , "Honoured" , "Tipped" , "Still thought of" , "Recalled" .)
