This is yet another ATC grey area!
The ATSIN actually says 'vectoring instructions as present' and then, tagged on the end, 'when established descend on the ILS' To me that implies you say everything you used to, including the report established bit, and then the new bit tagged on.
MATS 1, in the approach radar section still says:
"The controller shall instruct the pilot to report established on the ILS or MLS localiser and, if necessary, shall continue to give heading instructions until this report is received."
I always thought the established report was the end of responsibility for vectoring and until you received that report then you caried on giving heading changes.
