The core claim is about an alleged private mental state: that certain British people working in or around the European Commission “absolutely hate this country.” Public sources can confirm that UK nationals did work for the European Commission around that period, but they do not provide evidence about those individuals’ feelings or intentions. Because hatred is not publicly verifiable in this context, the claim cannot be confirmed or contradicted from available evidence.
