"Personally I'll lay the blame at the feet of weak government...."
As will a lot of other people who find it easy to do that when they don't have much of an idea about the difficulties faced by the negotiators (on both sides).
People who voted remain will claim that they knew best of course, but they haven't a shred of evidence to support the idea that they knew better than anyone else. In any case, it isn't about who knew best, the referendum was about what the nation wanted. We all had the chance to vote, and we voted to leave. We will leave, and I'm quite sure that there will be millions more words written about what should or should not happen afterwards.
Remainers will go on claiming they were right forever and a day, and Brexiteers will do the same. Meanwhile, all of us, of whatever persuasion, will have to get on with life.
I confess I smile when i see people saying who they'll blame, as if that's what should happen - we must have someone to blame other than ourselves. Human nature comes to the fore, as it always does.
