Ignore new vote to secure leader of government (7)
I believe the answer is:
neglect
'ignore' is the definition.
(I know that ignore can be written as neglect)
'new vote to secure leader of government' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'vote' becomes 'elect'.
'to secure' is an insertion indicator (inserted letters are secured inside).
'leader of' says to take the initial letters.
The first letter of 'government' is 'g'.
'elect' going around 'g' is 'eglect'.
'n'+'eglect'='NEGLECT'
(Other definitions for neglect that I've seen before include "Fail to notice or care for" , "Treat carelessly" , "Leave unattended, disregard" , "Leave undealt with" , "Disuse" .)
