Basically it seems to be saying much the same as the arguments being put forward by the Remain supporters on this site, although, in some cases, not as eloquently.
I love the bit at the end of page 3 about a "vote of no conference". It also suggests that this (the vote of 'no conference') could happen (future tense) and that it 'precipitated' a general Election (past tense). Clearly not the sharpest pin in the box!

But, if it supports your entrenched viewpoint (and yes, I accept that mine is also entrenched) feel free to quote it.
