The UK is an island and islanders apparently have a taste for independence so I guess saying EU membership was never cordial is kicking at an open door. Oh and it was also not the first time that the English broke away from a bond with Europe. If the 2016 departure was a politically inspired and badly executed decision, in 1534 there was another exodus based on religious and financial grounds. Although you can question that: politics, finance and religion are always very unhealthily and closely linked.
