A last ditch attempt to avert a Tube strike on Boxing Day, a crucial shopping day for retailers, has failed.
Members of the train driver’s union Aslef were due to stage a 24-hour walkout on December 26 but London Underground had been seeking an injunction against the strike action.
The High Court rejected the injunction following a four-hour hearing.
The travel disruption is expected to deter many shoppers from moving about London on the crucial Sale day, and could cause sales and footfall to drop by between 20% and 30% according to retailers in the capital.
Retailers usually take in the region of £120m on Boxing Day, in the West End alone.
The Aslef tube drivers are striking over pay and conditions. They are demanding triple pay and a day in lieu for working on Boxing Day.
