Former European minister's first point arranged immunity (9)
I believe the answer is:
exemption
'immunity' is the definition.
(exemption is a kind of immunity)
'former european minister's first point arranged' is the wordplay.
'former' becomes 'ex'.
'first' indicates taking the first letters.
'arranged' is an anagram indicator.
The first letters of 'european ministers' is 'em'.
'point' is an anagram of 'ption'.
'ex'+'em'+'ption'='EXEMPTION'
(Other definitions for exemption that I've seen before include "Freedom (from, eg, tax)" , "A release from, eg, tax liability" , "Immunity from an obligation or duty" , "Freedom from liability" , "Discharge" .)
