The OFT move comes at a time of unprecedented profits for the British banking industry, triggering charges of 'outrageous profiteering' from consumer groups. Next week, Britain's biggest bank HSBC is expected to unveil a 21% higher profit of around £7.5bn - easily the biggest ever for a High Street bank. This will eclipse the current record of £6.16bn announced last week by the Royal Bank of Scotland, which owns NatWest.
