In London Barclays declines after a bottom-line loss because of provisions related to probes of its Forex operations but in Paris media group Vivendi rebounds, aided by news of share buying by a vehicle of its chairman. In Lisbon lenders BPI and BCP leap on reports Isabel dos Santos, BPI’s No. 2 shareholder and reputedly Africa’s richest woman, wants to engineer a merger of the two banks.
