[Exile on Spencer St]

Unfortunately, Margaret, I tend to agree with Cashy on this.
It stinks of a deal dreamed up by Whitehall mandarins and their comrades in Brussels. The dithering and delay has been deliberate so that there is no time to come up with an alternative and (most critically) to get a new Tory leader.
The EU will reject bits of it, so Quisling May can continue to pretend she's offering a tough deal, but not so much that May can then claim it's 90% of what she has asked for (of course no one in the metropolitan media will point out that what she is asking for is less than 10% of what people voted for).
The MPs, of both parties, will then approve the terms of surrender to avoid them risking defeat in an election and the loss of their privileges.
Hope I'm wrong but, given the evidence, I'm not holding my breath.
