The longest rail strike since 1968 has begun, with hundreds of trains cancelled on the Southern network across south east England. A five-day walkout by members of the RMT union started at midnight in a row over the role of conductors. Southern plans to run 60% of its normal timetable. Parent rail firm Govia Thameslink (GTR) is in a bitter dispute with the RMT union over plans for drivers to operate the doors on new trains using CCTV. BBC Correspondent Ben Thompson said the five-day walkout is the longest industrial action on the railways since 1968.
The prime minister "strongly condemns" a five-day strike that is causing "disruption and misery" for hundreds of thousands of Southern passengers.
