For example, interrupting tardy representative (6)
I believe the answer is:
legate
'representative' is the definition.
(I know that legate is a type of emissary)
'for example interrupting tardy' is the wordplay.
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'interrupting' is an insertion indicator.
'tardy' becomes 'late' (synonyms).
'eg' going within 'late' is 'LEGATE'.
(Other definitions for legate that I've seen before include "Papal envoy from Galtee" , "Vatican emissary" , "papal emissary" , "Envoy, maybe papal" , "Official representative" .)
