Yes I'm asserting that my reading of the DUP manifesto implies that they are going to support leaving the single market, you are asserting your view.
Manifesto: "progress on new free trade deals with the rest of the world”.
Journalist: This implies that the DUP favours leaving the EU Single Market and the Customs Union
I agree with the Irish Times and their analysis, you agree with other analysis, we can agree to disagree, no need to call my journalist ill-informed, I think the Irish Times is quite a well respected paper.
I'm not providing a view - I am using the direct evidence of their manifesto and the comments of their leadership, which (as far as I am aware) have never provided a commitment to leaving the single market and customs union.
Your assertion is very weak - in that "progress on new free trade deals with the rest of the world”, is just as likely to mean that were we to leave the single market (something DUP have never said they wanted) then getting deals in place is important.
But there is also:
'Ability to opt-in to EU funds where proven to be cost-effective and add value'
How is that consistent with anything other than remaining part of the single market/customs union.
Bottom line - you stated unequivocally that it was clear that '... both DUP & Tories have in their manifesto a promise to remove UK from single market' - you have provided not a scrap of evidence to justify this. And it can be disproved also unequivocally simply by reading the manifesto in which no promise to remove the UK from the single market exists. In fact not only is there no such commitment but the single market isn't even mentioned.
