Royal Bank of Scotland confirmed today it has dismissed a number of employees for misconduct as a result of its investigations into the Libor interest rate rigging scandal and, along with other banks, is still under investigation by regulators.

"The Libor situation is on our agenda and is a stark reminder of the damage that individual wrongdoing and inadequate systems and controls can have in terms of financial and reputational impact," chief executive Stephen Hester said in reporting first-half results.

RBS said it was co-operating with investigations by governments and regulators into its submissions and procedures around the setting of Libor and other inter-bank lending rates.

Last month sources with knowledge of the matter said RBS had fired four traders in connection with the affair. New details from court documents and sources suggest that groups of traders working at three major European banks, including RBS were heavily involved.

The bank said today it was being investigated by regulators in the United States, Britain and Japan and by competition authorities in Europe, the United States and Canada.

RBS said it was not possible to reliably measure what effect the investigations would have, including the timing and amount of fines or settlements. Rival Barclays was fined $453 million last month by U.S. and UK regulators.

The issue has heaped pressure on Mr Hester, who was appointed CEO four years ago with a remit to rebuild the bank and its reputation following the bailout.

Government sources told Reuters yesterday that it had no plans to fully nationalise RBS, contradicting a report in the Financial Times.

The bank, which is 82 per cent-owned by the government, also reported today it made a first-half operating profit of £1.83 billion, down from £1.97 billion in the same period last year.
