LONDON will face shutdown twice in a week this month after Tube unions announced further strikes yesterday over new rosters for all-night weekend service.

Staff represented by rail unions RMT, TSSA and Unite will strike for 24 hours beginning on the evenings of August 25 and 27.

Workers are calling on London Mayor Boris Johnson to end his refusal to meet with unions, which say that the top Tory’s plan for the London Underground to open all night at weekends would compromise the family life of staff members and deprive them of necessary rest.
