Since Sunday 28th January, service 71 between Withernsea and Easington has gained a Sunday service. The route is operated by East Yorkshire with financial support from East Riding of Yorkshire Council, and the new Sunday journeys are funded from the council's Bus Service Improvement Plan Plus funding.
There are four daytime journeys in each direction on a two hourly frequency. All Sunday journeys operate via Holmpton, unlike Monday to Saturdays where some serve Patrington instead. There is a lot of layover in the new Sunday timetable, 30 minutes in Withernsea and 34 minutes in Easington, although the service is due to be extended (presumably on a seasonal basis) to Kilnsea and The Spurn Discovery Centre from Easter.
Going through my timetable collection, this is the first Sunday service to Easington since some time between 2003 and 2006. In the early 00's, service 71 had three Sunday journeys year round between Withernsea and Easington, supplemented by Summer service 73 from Withernsea to Kilnsea and Spurn via Patrington and Easington.
