And if that was not enough, to suggest that the figure could not yet be proved true or false "because the UK had not yet left the EU" is of such jaw-dropping fatuity that one is almost lost for words. The figure was demonstrably false the first time it was uttered, and remains so now. When we leave the EU, it will still be false.
What this says of Mr Gove, therefore, is that there in an unworldliness about him that could so easily be seen as his displaying contempt for all of us. In the way of things, for a man to lie so openly and with no concern for the consequences suggest either a form of mental illness or that he believes us all to be so stupid that we will accept his lie at face value. And that is arrogance.
Mr Gove, in fact, does present a demeanour that suggest he is superior to all of us – the essence of the arrogance for which we so love the political élite. Yet, even as a member of that political élite, he would cast himself as champion of the public which, he says, have "had enough of experts".
That is as maybe. Actually, we have had enough of all-purpose experts – people such as economists and lawyers who may or may not be expert in their own fields, but who then trade on this slender base to claim expertise in far wider areas than is warranted by their qualifications and experience.
We have also had enough of the condescension and sneers of people whose only real ability is to parade their ignorance without shame, repeating the same errors endlessly and ignoring correction, purporting to be superior to us mere plebs.
And into that category Mr Gove slides effortlessly, with his lies and his stupidity, and his entirely unwarranted assumption that he in any way represents us, or that his lies were welcomed and believed. This is the man so lacking in self-awareness that he was able, on the BBC Today
programme, to attack "groupthink" and people who "think they know best".
So, whether or not we have had enough of "experts", we most certainly have had enough of Mr Gove. We've had enough of his faux research operation, Change Britain
, and its trivial, self-important drivel.
And we've had enough of all those people clustered around Gove who are poisoning the post-referendum debate with their lies, their ignorance, their wilful misrepresentation of the facts and their refusal to engage in honest argument over substantive issues. We are sick to the hind teeth of their patronising assumption of superiority and their belief that they are defining the debate.
What this self-regarding dross needs to realise is that this is not about them. When it comes to the negotiations proper, the financial settlement with the EU is going to be an important part of the talks. Most likely, the remaining Member States will seek assurances from the UK as to continued payments before they are prepared to consider the detail of a new relationship.
With Gove and his fellow travellers perpetuating the myth that there are savings to be made from Brexit, and that we can cease making contributions to the EU, they are making it very hard for the Prime Minister to offer concessions, the lack of which could cause the negotiations to collapse.
Already, we are hearing reports
that Mrs May is struggling to come to terms with the complexity of Brexit. So, rather than her back-benchers making life more difficult, they need to be working with her to ease the way for a settlement that, even with the best will in the world, is going to be difficult to achieve.
Instead, we have rampant egos dominating the field, creating such mayhem that they could frustrate the very thing they claim to be supporting, all in the name of the unachievable, based on a lie.
Thinking aloud on this, for want of such people doing the decent thing and vacating the political field, it seems to me that those of us – from both sides of the divide - who are prepared to entertain a realistic settlement and will accept compromises to achieve one, need to be more assertive.
The likes of Gove do not represent us, and never did. Most of what Vote Leave did invited the comment, "not in my name". Their current plans for a train-wreck Brexit are not ones which we endorse.
As I was remarking in my previous blogpost, they may be the noise-makers but we are most probably the majority. And there is too much at stake for us to be a silent majority. We need to put Gove and his Big Lie back in the box and nail down the lid.
