The UK is a Sovereign State, as is France, Ireland, Spain, Germany etc.
The phrase no deal brexit, or clean break, has to be something of a misnomer as we are intrinsically tied to the EU, there simply cannot be a ‘right we are off – we will sort this out once we are free’ situation, that is not how the world works any more – thankfully.
The deal that is on the table is stacked in the EU’s favour, of course it is – the UK negotiating team were taken to the cleaners, or wanted it this way so it would not be passed by Government. Either way a slight tinkering of this deal is the best that can be achieved prior to 31st October, or 31st January 2020, delete as applicable.
There is no masterplan and despite himself thinking so Bo Jo is not a white knight riding in to save the day and snatch victory from the jaws of defeat, sadly he is just a cad and a bounder.
