London Underground is reportedly planning to launch night services in August, which is almost a year later than originally planned.
Round-the-clock weekend services will first begin on the Central and Victoria lines on 19 August, followed by the Jubilee, Northern, and Piccadilly lines later in the year.
The Night Tube was originally planned to start in September 2015, but it was delayed due to disputes over staff wages.
London’s Mayor Sadiq Khan was quoted by media sources as saying: "The Night Tube is absolutely vital to my plans to support and grow London’s night-time economym, creating more jobs and opportunities for all Londoners.
"The constant delays under the previous mayor let Londoners down badly. I have made getting the Night Tube up and running a priority."
According to Transport for London (TfL), Night Tube would reduce night-time journeys by an average of 20 minutes, with some cut by more than an hour.
It is also expected to create close to 2,000 permanent jobs and contribute £360m to London’s economy.
The British Transport Police will employ more than 100 officers to keep watch over the 144 stations when services begin.
