Whats hapenning to Sunday services 356, 400 and 401?

North Yorkshire County Council appears to be going ahead with it's planned withdrawal of financial support for evening and Sunday bus services within the county, including Monday to Saturday evening journeys between Goole and Selby. This is one of many evening and Sunday supported services operated by Arriva Yorkshire's Selby depot, and as a result Arriva has announced that Selby depot will be closed in the evening Monday to Saturday, and except for the main York service, also on Sundays.

That implies that the Sunday service between Selby, Snaith and Goole on services 400/401, and the interworked 356 between Goole and Swinefleet, are to be withdrawn. But on Sundays these are funded by East Riding of Yorkshire Council, not North Yorkshire County Council and therefore were not proposed for withdrawal in the North Yorkshire consultation. So what is the status of these Sunday services? Withdrawn? Staying? Going to another operator?
