The technique had put M&S in it “finest monetary well being for almost 30 years” Mr Machin mentioned, delivering outcomes for the monetary yr ending in March simply earlier than the hack disrupted companies on the finish of April.

M&S reported a 22% rise in revenue earlier than tax and different prices to £875m, whereas gross sales rose 6.1% to £13.9bn, with rising meals gross sales taking the lead.

Lucy Rumbold, fairness analysis analyst at Quilter Cheviot, mentioned it could be “a protracted slog” for M&S to get again to the place it was.

“However given the sturdy efficiency of late and offered the assault might be wholly eradicated, the enterprise ought to get there,” she mentioned.
