THE battle for Dutch bank ABN Amro will take another twist this week as the rival suitors update markets on their pursuit of the business.

Barclays, which has made a £45bn offer for ABN backed by the bank's board, must give an update by tomorrow under Dutch takeover rules.

The rival consortium bidding for the Dutch bank, led by Royal Bank of Scotland, must also update the markets by Sunday under the same rules.

RBS, backed by Spanish bank Santander and Belgium's Fortis, is prepared to make a £49bn offer for the Amsterdam bank.
