There are so many errors/lies, already around a hundred with a quick look ,throughout that document. A few favourites:
In other words, if we were to impose existing CET tariffs against the EU, HM Treasury would gain a bonus in tariff revenue but, importantly, the tariffs would make no other difference to our Brexit economic gains.

Spot the error/lie. This has to be a joke.
It is quite likely that we will liberalise our standards to modernise our economy post-Brexit. As such, exporters to the UK will probably not need to change much, if at all, as more varieties of products are deemed acceptable, subject to reasonable safety standards and the like.

Forgot to mention the UK imports more than it exports so what about this financial hit.
And there's more...
