They might not need us persay but they definitely wanted us to stay in and us leaving is gonna certainly sting, especially if it causes a couple of other members to leave as well. Brussels clearly didnt want this to happen they have made that much blatently clear which is why it has bitten them in the ass.
Of course they didn't want us to leave, but we will miss them far more than they will miss us. We don't have any allies now - we will be shunned by all. No other members will leave. Nobody else in Europe is that stupid. Especially when they see just what the repercussions are of biting the hand that feeds you. This was supposed to be a coming together of nations for the greater good, and someone had to lead it. Once again, it was not perfect, it was a work in progress, and we had negotiated better terms than others. As someone else on here has already said - we have just committed national sabotage and economic suicide, and all in the name of what? So we can look at fat Boris and that idiot Farage's faces day in day out. Way to go, UK.
