DESPITE INITIAL ADVERSE reactions to the Government’s new Individual Savings Accounts (in replacement of personal equity plans), a host of big names have sought and received Inland Revenue approval to sell ISAs. Among the successful applicants are the likes of Tesco, J Sainsbury and Marks & Spencer -’ all previously critical of the scheme.
