An interesting little political manouevre here, insisting that MPs should be able to vote on the trade arrangements post Brexit. Specifically, the claim is that membership or not of the Single Market is not the same as Brexit and thus MPs should vote on that single market membership or not.
To which the correct answer is no, go away:
Theresa May is under massive cross-party pressure to grant MPs a vote on any decision to leave or limit UK involvement in the European single market, amid growing outrage at the prospect that parliament could be bypassed over the biggest economic decision in decades.
Tory MPs joined forces with former leaders of Labour and the Liberal Democrats, the SNP and Greens to insist that parliament have a say and a vote, pointing out that, while the British people had backed leaving the EU, they had not chosen to leave the biggest trading market in the western world.
They're right it's a large decision and one can indeed make a case that that's what they're for, making decisions for us. But in this case the answer really is no, go away.
Because it's being made very clear to us that the Single Market is Brexit. We are being told that if we want membership of that trading area then we've got to accept free movement of people (not in itself a bad idea but not really what people voted for), all of the regulation of the economy which the EU imposes, must pay into the EU budget and so on and on. Essentially, it is being made very clear that membership of the Single Market comes with all of the costs and responsibilities of full EU membership.
That is, single market membership is a denial of Brexit itself.
We do all know that a majority of MPs are against the very idea of leaving. Which is exactly why they shouldn't have a vote on the matter. For accepting single market membership is tantamount to not leaving, it would be a reversal of the referendum by the back door.
