For all of your information, despite your questioning of my intelligence and your failure to come up with the information I was asking for, I finally wrote to Bankia who have very kindly given me the Swift code which applies to all Bankia branches so Roland, you might find this useful.
The Swift code is: CAHMESMMXXX
I'm sorry if I sound annoyed but I follow this forum and find it very useful with some very generous spirited people who want to inform and help people. Today I've seen another side of it which tried to make me out to be stupid which I don't appreciate.
Let's all move on.
Kind regards, Helena
