London Assembly Labour Transport Spokesperson, Val Shawcross AM, said:
“Whilst we support the principle of the night tube, the fact that taxpayers could lose over £100m before the project breaks even shows Boris Johnson is more focused on securing a legacy than doing it right.
“There are many different ways the night tube service could be set up, including a staggered introduction or pilots which could save tens of millions of pounds. As it stands the Mayor seems more intent on forcing it through quickly than securing best value for money.
“With travel fares rocketing by 40% since the Mayor came to power, you’d think he’d be a bit more careful with Londoners’ money. Particularly only months after he plans to cut almost 900 underground jobs.
“Whilst many people will like the idea of night tube services what nobody wants is another rushed through Boris Johnson vanity project which will end up wasting hundreds of millions pounds.”
