Southern rail and the Rail, Maritime and Transport (RMT) union have resumed talks with conciliation service Acas to settle a row over driver-only trains.

Relations have plummeted during the dispute, with each party blaming the other for service cancellations.

Southern’s owner, Govia Thameslink Railway , and the RMT will meet Acas again next week to try to resolve the row over the role of conductors.

An Acas spokesman said the two parties met on Monday and would resume talks next week.
