Lack of substance of English politicians' points accepted (9)
I believe the answer is:
emptiness
'lack of substance' is the definition.
(I've seen this before)
'english politicians' points accepted' is the wordplay.
'english' becomes 'E' (abbreviation).
'politicians'' becomes 'MPs' (Members of Parliament).
'points' becomes 'tines' (I've seen this in another clue).
'accepted' is an insertion indicator.
'mps' going around 'tines' is 'mptiness'.
'e'+'mptiness'='EMPTINESS'
'of' is the link.
(Other definitions for emptiness that I've seen before include "Void; hunger" , "Lack of substance" , "Vacancy, void" , "vacuum" , "Vacuity" .)
