That's because the EU's position has always been that negotiations can only take place after the A50 notification.
It was an attempt by us to segment the negotiations to strengthen our position.
But if the EU really wanted to make sure the citizens of Europe who work in Britain were protected they could quite easily get started on a reciprocal arrangement. It showed a really poor attitude on their part. It has been on the ITV news the last 6 months, Juncker " we want to protect the rights of EU migrants in Britain and in Europe"
The British government have been prepared to negotiate on this for some time, I only ever watch ITV news and I can offer no direct quotes but the British government and several ministers have been prepared to negotiate with them straight away and take away the nervous uncertainty people must be feeling on this issue. It is the EU trying yet again to control the British electorate.
A reciprocal agreement would be pretty easy to agree, all residents in this country from EU countries right now have to be treated the same as they have always been, it should be pretty easy to prove how long you have been in this country through wage slips or college admission forms and the same goes for Brits working or studying in Prague or Barcelona etc.
It is no where near as completed as the EU bureaucrats are trying to make out, unless the is some truth to the rumour that the EU wants EU citizens living and working in Britain to have higher benefit increases in line with the EU standards, meaning we would have a situation where the British tax payer would have to pay foreign nationals living and working here higher benefits then the indigenous population, something that would be a vote loser for any party.
I am actually all for harmonisation of taxes and benefits across the continent. Completely unworkable in practise to anyone with a brain cell, but that does not effect me. I just would love to see the reaction from the French when they do not get their pensions till they are 67 or the British national debt when we all get to draw our pensions at 50.
Europe one size fits all, obviously it does not, and if Juncker and his gangster cronies in Brussels could have just understood that and made some concessions to the British they would probably have been able to keep shaking our money tree for a few more years.
