On Monday, Dutch bank ING said it would split its operations, leaving the firm's balance sheet 30 per cent smaller than before its bailout, in a sign of how tough the EU can get on banks that have received state aid.
Markets gave the two Irish banks the harshest treatment, as doubts persist over the country's plans to pay 54 billion euros to cleanse banks of risky commercial property loans, for which the finance ministry is yet to receive approval.
