Caroline Pidgeon AM, Liberal Democrat London Assembly transport spokesperson, commenting on the announcement that the launch of the Night Tube has been deferred said:
"This is a big climb down for the Mayor. His retreat is entirely due to his error in setting a specific start date before all the staffing arrangements and other issues had been settled.
"By pushing for a set start date the Mayor strengthened the union’s negotiating position.
"The Mayor must now also come clean and explain when the expected changes to Night Buses will take place.
"It would be totally wrong if any Night Bus routes see a cut in their weekend service before the start of the Night Tube."
