Country and Language setting for iTunes store account

[Easygoingdave]

I have recently moved to Spain, when I attempted to change my address and credit card details (Spanish credit card) before I could complete the relevant registration boxes, I had to change the Country or Region to Spain. As a consequence the iTunes store displays everyting in Spanish. I then went and changed the Country back to the United Kingdom, but the screen immedately defaulted to my credit card address and would not accept the details unless I filled in a correct post code (Obviously the billing address in Spain does not have a Post Code). Is there a way I can register my Spanish address and billing details but still view the Itunes store in English?
Thank you in advance.
