All 400 branches of Wilko will close by early October with the anticipated loss of all 12,500 jobs across the business, according to the GMB union.

GMB said it was informed of the news by administrator PwC on Monday morning, with the union saying it was “likely” that all of Wilko’s staff will be made redundant.

The announcement of the loss of all 400 stores follows news this morning that a rescue deal with HMV owner Doug Putman fell through due to “rising costs”.

Redundancies started in early September as a number of bids to save the embattled retailer failed.

Wilko collapsed into administration last month after struggling for most of the year, despite cost-saving efforts and a turnaround plan.

Retail Week has reached out to GMB for comment.
