One notices on Border/Immigration programs that the USA and Canada do sometimes request access to your cell phone, laptop, and/or social media information at the airport. It's also all over the news and confirmed to be legal according to the laws of both countries.
I am yet to see or read about that for the UK. Are the privacy laws specifically for electronic data such as cell phone, laptops, and social media accounts different for a non-British national at UK border crossings?
