Issued new mandate after start of election (8)
I believe the answer is:
emanated
'issued' is the definition.
(to emanate is to issue or emit)
'new mandate after start of election' is the wordplay.
'new' indicates anagramming the letters.
'after' means one lot of letters go next to another.
'start of' suggests taking the first letters.
The first letter of 'election' is 'e'.
'mandate' is an anagram of 'manated'.
'manated' put after 'e' is 'EMANATED'.
(Other definitions for emanated that I've seen before include "came forth" , "Issued forth, as from a source" , "Issued or originated from a source" , "Flowed" , "Emerged or originated" .)
