Passengers on Southern Railway face more travel chaos after the drivers' union decided to launch a fresh ban on overtime.

Members of Aslef will refuse to work overtime from the end of the month after the breakdown of talks aimed at resolving a year-long dispute over staffing and driver-only trains.

The action is expected to cause more disruption to Southern's services, which have been hit by cancellations and delays for over a year because of industrial action, staff shortages and other problems.

Members of the Rail, Maritime and Transport union on Southern are going on strike on May 30 as part of their long-running row with the company over the same issue.
