Shares in Irish banks have again plummeted in Dublin after the nationalisation plan for Anglo Irish Bank.

Shares in AIB ended down almost 60% at 60c, while Bank of Ireland fell almost 55% to 34c. Irish Life & Permanent dropped 50% to €1.10.

Overall, the ISEQ index closed almost 7.5% lower at 2,274.

The falls come in the wake of market suggestions that Bank of Ireland and AIB look unlikely to be able to raise extra cash from private investors to top up a proposed State investment in the banks.

Earlier it emerged that Bank of Ireland Group chief executive Brian Goggin would retire this summer.

This is one year earlier than had been anticipated.

Mr Goggin has been with the bank for 40 years.

The court of directors at the bank has accepted his decision to step down and has started the process to select a new chief executive.

In a statement, Mr Goggin said he was proud of his career at the bank serving the interests of its stockholders, customers and employees.

He said: 'The most recent period has been particularly difficult leading the Bank through a time of great turbulence in global financial markets.'

He added that the Government's decision to support the recapitalisation of the bank was an important milestone and would ensure its long-term strength.
