When I wrote in July that Dame Alison Rose’s forced exit as chief executive of NatWest in the wake of the Nigel Farage scandal was ‘unnecessary’, many readers vehemently disagreed with me. Out she went, Treasury ministers having steamrollered the NatWest board’s brief attempt to hold her in post – and a subsequent Information Commissioner’s Office (ICO) report concluded she had breached data protection laws by revealing to the BBC that Farage had been a customer of the Coutts arm of NatWest and adding the misleading suggestion that his accounts had been closed for purely commercial reasons.
