I'm well aware. But considering that Turkey, the modern successor state of the Ottoman Empire, is negotiating its way into the EU, while the UK has just finished making a dog's breakfast of negotiating its way out of it...
Technically, they are still negotiating, though negotiations stalled in 2016[1].
I can't ever see it happening; there is so much opposition. Human rights seems to be biggest sticking point, and is unlikely to be resolved any time soon.
