Prior to the opinion poll aka partial referendum, we had a degree of certainty as regards the economy, employment, Northern Ireland, legislation, trade deals in place, a very strong pound, a lead role in the decision making process in Europe, commitment from the world's financial markets and major manufacturers to have bases in the UK and membership of a trade bloc that was strong enough to compete with the Americans and Chinese.
That was all in the bag.
Now we have uncertainty about all those things, so say what you like about "Project Fear" but it is indisputable that everything that we have worked for over the last 40 years and beyond is now in the balance and we have replaced confidence in our country's economy and future prospects with uncertainty - and have done so at considerable expense.
Simply running the partial referendum and the ongoing costs of the negotiations has already cost the UK more than the EU budget payments the Leavers were whingeing about. Parliament has been paralysed by Brexit leaving important legislation not dealt with and when we finally do leave, we'll then start picking up the enormous bills for e.g. rewriting the law - which unless they intend to further cut people's rights will simply be rewriting what is already in place as an EU member. Economically it's already a disaster.
