 I think the kind of first thing you really notice when you're running the undercover voters is something that we all know, but until you actually really experience it in practice, you perhaps aren't so acutely aware of it. And it's how bespoke your social media feed is and how different different people's social media feeds can look. So my undercover voters reflect a wide range of different voters here in the UK. They're based in eight different battleground constituencies across England, Wales, Northern Ireland and Scotland.
