Admittedly, I don’t know much about Brexit, but from what I have been exposed to, it seems like a decisively economical and political impairment that made travel and business with the rest of Europe more difficult and costly. Since it is so highly criticized as a terrible move, why doesn’t the UK just rejoin the EU?
I’m no fan of Thatcher but she did some good things during her tenure - negotiating the UK’s place in the EU and setting up Channel 4 spring to mind - and I honestly think she would be utterly devastated if she saw what her party had become today.
