Leading retailers in the United Kingdom are facing significant legal challenges as a series of equal pay lawsuits could result in millions of pounds in damages. These lawsuits are putting pressure on the retail sector, with the potential for 'enormous' liabilities as the system of litigation funding comes under scrutiny. The ongoing legal actions are not only highlighting issues of equal pay but also raising concerns about the practices of litigation funders involved in these mega class actions. The situation reflects a growing concern over fairness in pricing and loyalty programs, as retailers are also criticized for excluding millions from lower loyalty prices.
