The deal is done but how long will it survive? What's in it and is it good or bad for Northern Ireland?

So the deal is done but how long will it survive? Yesterday Theresa May took 5 hours to persuade her cabinet to back her Brexit withdrawal agreement with the EU. Although several ministers are understood to have spoken against it. But now the backlash has started. From Tory arch Brexiteers to Mrs May confidence and supply partners in the DUP. Sammy Wilson has described the agreement as "A poor deal. A bad deal. A deal she said she would never accept" and speaking on Sky News he also compared the deal to a "punishment beating". But what's in this deal and more specifically is it good or bad for Northern Ireland? Stephen spoke to BBC NI Economics and Business Editor John Campbell and BBC NI Politics Editor Mark Devenport.
