British retail empire Arcadia Group, which owns well-known fashion chains including Topshop, went into bankruptcy protection on Monday, putting 13,000 jobs at risk.

In another blow to a retail industry hammered by the coronavirus pandemic, Arcadia said it had called in administrators from Deloitte after the pandemic “severely impacted” sales across its brands.

Competition also has increased from low-cost rivals like Primark, as well as from online disrupters such as ASOS and Boohoo. Critics have also said that the 68-year-old Green, who has been embroiled in a series of controversies over the past few years, hasn't invested enough in the businesses to get them in shape to deal with the new competition in retail.
