Charges current politician over void lease for land ownership (3,6)
I believe the answer is:
fee simple
'land ownership' is the definition.
(fee simple matches up with the definition land ownership)
'charges current politician over void lease' is the wordplay.
'charges' becomes 'fees' (fee is a kind of charge).
'current' becomes 'I' (symbol for electric current).
'politician' becomes 'MP' (Member of Parliament).
'over' is a charade indicator (letters next to each other).
'void' says to hollow out the word (remove centre letters) (the word is empty or void of its inside letters).
'lease' with its centre taken out is 'le'.
'fees'+'i'+'mp'+'le'='FEE-SIMPLE'
'for' is the link.
(Other definitions for fee simple that I've seen before include "form of inheritance" , "Absolute tenure of land with right of disposal (law)" .)
