Entry points were ATSIX and ERAKA.
The cross would have been at NEVIS if both aircraft were following their flight plan routes.
In this case the ATSIX traffic was going direct.

We endeavour to give aircraft their oceanic crossing levels as soon as they ask for it, subject to traffic.
I am not going to make any further comment regarding the incident.
Edit. The link to the maps was just found by "Googling", some of them are considerably out of date, however Montrose North has not changed.
