Nadine Houghton, GMB national officer, described it as the “death knell” for the discount homeware brand.
She said: “Wilko was far more than a brand, a retailer or the products it sold, it was the thousands of loyal team members now facing an uncertain future.
“Wilko may have ceased genuinely being a family brand many years ago, but the staff kept the real family ethos of Wilko alive until the very end. It is the family that Wilko colleagues made for themselves that will be missed the most.”
She added: “This isn’t a tragedy without cause. Wilko should have thrived in a bargain retail sector that is otherwise strong, but it was run into the ground by the business owners…. No worker caused the downfall of Wilko.
“But they will be the ones who will suffer – all as the owners get off scot-free. GMB will not stop campaigning for the owners of this debacle to be held to account.”
