Looks like they did not do much, if any, research before the referendum was agreed to be held. Looks to the same for Article 50 as issues such as the backstop in Ireland would have come to light. Had they researched they could have advised that what was voted for was not legally possible as it contradicted the GFA which was established in 1998 and therefore Article 50 could not be triggered?
It would have been a huge embarrassment for the government and people would have asked why was the Referendum held in the first place. However, it would have been short lived and nothing compared to the ongoing embarrassment as UK has become the laughing stock of the World.
I work alongside people from Countries such as; India, ROI, Australia, Russia, China and South East Asia. Many have asked the same question;
If UK is the 5th largest economy in the World why does UK think it can do better by going it alone?
I have never been able to answer that question. Nor have any of my UK colleagues who voted leave been able to answer. Guess people voted leave for reasons other than money?
