//Well, yes, but firstly, nine months isn't "day 1"//
Well, I assume "day 1" to be the day A50 was triggered. There were thus nine months for the government to formulate its approach to the negotiations so that they could be presented on "Day 1"
"...and secondly we *did* set out our terms -- or, rather, Theresa May did. Unfortunately, those terms, which actually got a good deal of support at the time, didn't lead anywhere brilliant."
They might have done had Mrs May not capitulated at virtually every juncture (though personally I doubt it).
