Is it against the law to open other peoples mail in the uk?

Question

Is it a crime to open mail that isnt addressed to you from the bank and other organisations?

Answer 1

Yes it is.

Answer 2

Not if you don't tell anyone...lol. Joking...it is if you do it for unlawful purposes...but if you do it to find the return address etc. then I don't see how. In certain countries, such as Italy, they do have a "privacy law" and so you could get into trouble just by opening someone's post. But I'm pretty sure there isn't one as such in the UK.
