Radical reform of the cash machine network will be demanded by the Treasury's independent report on the banking industry next month, reports the Financial Times.

The call will come in an effort to stimulate competition for current accounts and cut the market power of the big four high street banks. Don Cruickshank, who is handling the investigation for the Treasury, is expected to condemn as anti-competitive plans by Barclays to charge non-customers £1 for cash withdrawals. Instead he is likely to recommend a 30p maximum charge.
