Dozens of trains have been cancelled due to platform closures at London's Liverpool Street station.

The platforms were shut after a "track defect" was found just outside the station at 11:50 GMT.

Network Rail engineers worked to repair the track and re-opened the platforms at 14:10.

However, disruption to Greater Anglia, London Overground, TfL Rail and Stansted Express services is expected to last until 17:00.
