National Australia Bank, the bank that is struggling to recover from a A$360m (€206.9m) currency options scandal that erupted at the start of the year, has hired seven bankers to its European financial markets group in London.

Muriel Minvielle joins NAB as head of credit sales, with responsibility for the bank's debt product sales to clients in the UK and continental Europe. She was previously in charge of selling debt products linked to the London interbank offered rate at HSBC in London.
