The irony is delicious,if you like that kind of thing. The fundamental concern of the Brexiteers was having control.and people outside the UK not telling them what to do. ..And that is what they had and have until 29th march. Now they have ceded all control for a new revised deal to the whim of 27 people ALL not accountable to the UK . The only way for them to take back any control is to revoke A50.
Make no mistake, the Czech minister has every right to make his support on the UK conditional. And there are 26 others who may do so or bite their collective tongues. There are enough grivenances ,real and imaginary, between EU member states and each ither and particularly with the UK , to generate angst for decades.
Of course the hard Brexiteers will rejoice in this freedom,but for how long?. The Backstop arrangement and an East West border which under the WA was a distant possibility, is in effect what the new UK Customs regulations, commencing April will happen.
