The Mayor of London, Sadiq Khan, has made a last-ditch appeal to the trade unions to cancel their planned Tube strike.
Sadiq has called on the unions to get back round the negotiating table for the sake of the millions of commuters who will be affected.
There will be major disruption across the Tube network when union members go on strike for 24 hours from 6pm this evening (Sunday).
The action concerns a historic dispute between the unions and TfL that started under Boris Johnson over the closure of ticket offices at Underground stations.
The Mayor of London, Sadiq Khan, said: “My message to the unions is clear: it is not too late to cancel this strike and get back around the negotiating table for the sake of all Londoners.
"I have instructed TfL to continue negotiating and we will be available around the clock to resolve this dispute.
“This strike is going to be a huge inconvenience to commuters, tourists and TfL staff. And it is pointless. There is a good deal sitting on the table that will ensure station safety and staffing levels across the Tube network. I am willing to carry on negotiations.
“This historic dispute has nothing to do with the millions of Londoners this strike is punishing. It must be called off.”
