ASDA strike action is spreading, with workers at three more stores voting to walk out over the “toxic” working environment at the retail giant.

GMB union blamed superstore owners the billionaire Issa brothers and private equity firm TDR Capital for “continuing asset-stripping of Asda at pace” after its first-ever strike in Gosport earlier this month.

Nearly 400 union members at the Wisbech, Brighton Hollingbury, and Brighton Marina stores will now vote on whether to take industrial action until March 5.
