People keep looking at the consumer privacy vpns , but there's a huge field of commercial vpn usage for a broad spectrum of tasks in the european union. Point to point tunnels connecting two sites into a single network. Allowing access to (corporate) resources via laptops and mobile devices. Fixing the one way nature of crappy internet that most people are forced to work with these days (or simply never realized), etc etc.

Basically if you want to do any sort of remote work, I'm not saying you're necessarily using one right now, but the odds are good. Possibly the politician's own IT back-end might have ... opinions... on the ability of the executive to overly check the legislative too.
