Putin's invasion of Ukraine happened when it did because Brexit was influenced by him via Farage.
Putin has a vested interest in a divided Europe and we played into his hands. He was wrong, however, in that NATO and Europe did come together despite the rift Brexit caused.
I really hope we can continue to keep that common interest together.
For those for whom the disaster of Brexit has made no difference, can I please ask what have been the benefits has they see them? More money, as was promised, for the NHS, lucrative trade deals? It may, as you claim, have made no difference, but you certainly are not better off and neither will your grandchildren be.
