Data Protection in the UK?

Graham Moore asks: "I am getting really concerned about where my personal information goes nowadays. In the last two weeks I have read two news articles here in the UK that talk about call centers and other agencies being set up in India that will transparently deal with customers from the UK (see the this article from The Register). On the UK mainland we have the Data Protection Act to fall back on if we believe the data is knowingly being misused or we wish to see what is stored about us. I suspect that once off of the UK mainland our details can be used or abused unhindered. I have contacted my MP, Melanie Johnson, who is also the Minister for Consumer Affairs, and have not yet had a response. Am I worrying about this unnecessarily or should we all start to get very concerned?"
