Rumours have resurfaced regarding Barclays and its interest in acquiring one of more Spanish savings banks, or 'cajas.' Press reports suggest that the British bank could be looking at four different Spanish savings banks as possible acquisition targets.Thus, the Sunday Telegraph pointed out this weekend that Barclays is one of the banks that made an offer for CAM, while adding that it could also be in the preliminary phases of negotiation with three other savings banks, including Novacaixagalicia.If Barclays were successful with its offer for CAM, it would increase its market share in Spain from less than 2% to around 4.5 - 5%.NA
