In his view "the blame shifting is the prelude to the scheme being dropped by the FCA. He added: "They have made a real mess of BSPS from start to finish."
During 2017, BSPS members were asked to make decisions about their pensions as part of a restructure of the scheme.
About 8,000 members transferred out of the scheme, with transfers collectively worth about £2.8bn.
But concerns about the suitability of the transfers were soon raised, leading to an intervention from the Financial Conduct Authority that resulted in a number of advice firms – key players in the debacle – stopping their transfer advice service, while others went out of business.
The debacle created a mountain of liabilities, which lawyers believe could end up costing the industry up to £300mn.
