Dutch takeover target ABN Amro today remained tight-lipped over the future of its chief executive after a court criticised the bank's management, cranking up the pressure on him to go and sparking fresh investor calls for its supervisory board to take control of the sale.

Bank of America went to Federal court today, seeking to enforce its deal to buy LaSalle Bank from ABN Amro, while activist shareholders called for removal of the Dutch bank's chairman.
