One of the four unions contemplating strike action on the Tube this week has already rejected a new offer by London Underground management.

The new deal, drawn up alongside the conciliation service Acas, had no more money on the table for night work but “re-shaped” the deal to create a better work-life balance.

But Unite has said the offer does not go far enough especially on issues relating to flexibility on the Night Tube, which should come into effect in September.

The other unions, TSSA, RMT and Aslef, are likely to fall into line behind Unite, bringing the Tube network to a standstill on Wednesday evening, August 5, and all of Thursday, August 6.

Breaking news: Aslef has now confirmed that the strike will go ahead
