The Night Tube round-the-clock services were due to start on September 12 on Fridays and Saturdays on the Jubliee and Victoria lines, and key sections of the Central, Northern and Piccadilly lines. However, train drivers have been concerned at having to work unsocial hours.

"Further to the progress made in recent days with the trade unions and the suspension of strike action, we believe we are not far from an agreement that protects the work-life balance of our employees and is affordable, sustainable and fair," says Mr Nick Brown, LU's managing director. "As such, we have decided to defer the introduction of the Night Tube to allow more time for those talks to conclude. Our objective is to reach an agreement that ends this dispute and delivers the Night Tube for Londoners this autumn."
