If DUP politicians are worried about that a Brexit deal would threaten their constitutional place in the UK, then it should not be voted through.
PLEASE WATCH THE VIDEO BELOW:
While the PM was talking about leaving the EU on the 29th March in her statement today, the Remainers just kept chuntering on about taking the decision back to the people, despite knowing that this would mean extending the Article 50 process so delaying Brexit Day and inserting yet more uncertainty into the UK economy.
But all the Prime Minister could offer the House was more of what we've seen over the last few months.
And what it amounts to, is that she will go back to Brussels to talk about the Irish border backstop issue.
She also talked about parliament's involvement in future talks and said she was thankful for the recent meetings she had recently had with party leaders and members across the house in the last few days – bar Jeremy Corbyn.
But that for me is all meaningless, because when she was asked what she was looking for from Brussels on the backstop, all she said was that she wanted something that would command the support of the House.
She was asked if she would be getting a legally binding change made to the Withdrawal Agreement, that the EU still says will not be re-opened, and her answer was that she would be looking to get something that commanded the support of the house.
This sort of talk should be setting off alarm bells across the country, let alone within the House of Commons.
What she's saying in essence is that she knows she can't get a legally binding textual change to the Withdrawal Agreement, but she'll maybe bring back some more letters of assurance about the backstop from Eurocrats and hope they do the job.
Now, the ten MPs of the Northern Irish Democratic Unionist Party are going to be far more suspicious of anything offered by Brussels on this, than anyone else in the rest of the House would be.
So, as they approach the 29th March Brexit deadline, while other MPs crumble to her deal in the face of false no-deal Brexit scaremongering, the DUP will probably still rightly stand firm to protect their place in the UK.
But, if Theresa May gets enough votes without DUP support, what then?
Could we possibly see her deal squeak through unexpectedly by one vote without the support of the ten DUP MPs? A deal that turns the UK into a vassal state of the EU and casts Northern Ireland adrift as some sort of part payment to the EU for us leaving?
Could that be possible? One supposes so, because you can see Theresa May's tactics of wearing MPs down little by little can't you and with the DUP likely to be the last to wear down then it must be a possibility.
And as far as I can see she has not told the DUP in any binding manner that she will not put the deal to the vote without first having their full support. I mean , if she was that concerned about having their support to hold her government together, she would make that promise, wouldn't she?
Or is she banking on the DUP rather having her than Corbyn?
This is getting beyond constitutionally messy.
The very fact that this risk exists, however small you may think it to be, means it must be headed off at the pass.
Just like the EU27 said they would stand behind the people of the Republic of Ireland during the negotiations in order to separate Northern Ireland from the rest of the UK, it is now time for all UK MPs to say they will stand fully behind the DUP should the ten Northern Irish politicians feel compelled to vote Theresa May's deal down for fear that it would break the UK up.
As far as I'm concerned, any MP voting for her deal when the DUP is unhappy about its effect on the place of Northern Ireland within the UK, should be deselected and definitely out at the next general election.
