Agent from England, Bond’s boss is protecting Queen, for instance (8)
I believe the answer is:
emissary
'agent' is the definition.
(I've seen this in another clue)
'england bond's boss is protecting queen for instance' is the wordplay.
'england' becomes 'e'.
'bond's boss' becomes 'm' (M is the head of MI6 in the James Bond series).
'protecting' indicates putting letters inside (inserted letters are held or protected).
'queen' becomes 'r' (r is abbreviation regina. e.g. in ER ).
'for instance' becomes 'say' (both can be used to introduce an example).
'r' placed into 'say' is 'sary'.
'e'+'m'+'is'+'sary'='EMISSARY'
'from' acts as a link.
(Other definitions for emissary that I've seen before include "Delegate" , "Representative sent on a mission" , "Government messenger" , "Diplomat sent on special task" , "one dispatched officially" .)
