Without taking any side here I can’t see any scenario where any future referendum will not be decided on a majority basis.
Anything else is immoral, undemocratic and frankly a cheat for those who prefer the status-quo.
As for the pact, I don’t really see how it will help any of the parties as the situations are so different.
Scotland is around 50:50 with support moving based on current events.
If the referendum was ran again during events such as the aftermath of Brexit, Boris scandals or Michelle Mone’s extortion then it would have been a yes vote.
Conversely if it had been ran during the campervan or gender fiascos then it would have been an easy no.
Interestingly, I read recently that if the 2014 ref was restricted to people born in Scotland then it would have been a yes vote on the same percentage as the Brexit one.
No matter what beliefs you have, if a majority of native born Scots wanted to leave then clearly there’s something wrong with the current set-up.
Ireland however is very different, demographic changes mean unionism doesn’t have an automatic majority any more and for the first time both sides are having to campaign on policies without purely being a tribal headcount.
Interestingly many people from traditional unionist backgrounds are now open to a united Ireland with the undecided voters holding the balance.
Sinn Fein holding the 1st Minister position would have been hard to believe even 8 years ago and having spent time there recently there has been a huge shift towards Irish culture.
I genuinely think it is just a matter of time before unification takes place, the GFA was designed for a peaceful transition of power so hopefully it serves it’s purpose.
Wales I have absolutely no idea over but was surprised that PC have so much support.
I think Britain needs to fix the social contracts and binds it once had or there will be change sooner rather than later.
