Now I'll ask you a question.
Where in the manifesto does it say the Tories want to remain in the single market?
All I've read is that they would prefer to stay in the EU after renegotiating the terms. That renegotiation fell flat on its face as you know and their pledge was then to give us an in/out vote - which as you can see they promised to honour, whatever the result.
We voted out and come April 2019 we should have a day to celebrate our independence. Peferably not 01/04
