I have to agree with Tink here as I work with about 6 Brits and anytime that we've had any private discussions? All have endorsed Brexit. For some of the reasons that Tink said and also that they no longer wish to be that closely tied to Europe. They seem to think that it only benefits the rich business owners and some in the government.
Not a subject I have a lot of knowledge about but all have mentioned that the immigration problem grows worse by the day. What the two have in common? I wouldn't know. Sorry.
