False. Brexit was inaugurated on Feb 1, 2020.
As for all those new trade agreements, economists will tell you that it's a universal economic law that the closer geographically nations are, the more trade that they will engage in with each other. Economists have labeled this phenomenon "gravity". Of course, this doesn't mean that the size of various trading partners is negligible, but rather that proximity will affect the amount of trade. So good luck with all those trade agreements.
