The launch date for the London Underground (LU) Night Tube is to be delayed, the BBC understands. The 24-hour weekend service on the Jubilee, Victoria and most of the Piccadilly, Central and Northern lines was due to start on 12 September. Members of four unions took strike action on 6 August and 8 July in the dispute over the Night Tube proposals. Three unions have also announced two 24-hour walkouts on 25 and 27 August. Talks were held earlier at the conciliation service Acas in a bid to avert further strike action and a further meeting between the train drivers' union Aslef and LU is expected later this week.
