Profit warnings from UK-listed firms at highest level in two years as Iran war drives up costs

Consultancy says companies quoted on London stock market issued 65 in three months to end of September

With less than a fortnight before John Healey's tax and spending statement to the Commons, the consultants EY-Parthenon said companies quoted on the London stock market had issued 65 warnings in the three months to the end of September.
