A cursory glance at social media makes it clear that there is huge concern – across political and cultural divides – about the degeneration of public life, behaviour and language. It is not hard to see why.

Against the explosion of sexual harassment claims (which exposes decades of ‘normal’ behaviour that went unchallenged because of its normality), we also see an eruption of trial by media. I have little sympathy for those who find themselves caught out, but do worry about those who are innocent, but now find themselves tried and sentenced by allegation. There must surely be implications for what I am calling the integrity of the public discourse.

But, we now have a US President who is a proven liar, misogynist and sexual predator (by his own taped evidence), and he continues in power. The lying and misrepresentation does not appear to disturb those who would have strung up previous presidents for just one faux pas. Lying and misrepresenting have become normalised. And there is no penalty.

Yesterday the Brexit Secretary, David Davis, told a House of Commons committee that the 57 Brexit impact assessment papers do not exist. In October these not only existed, but went into what he described as “excruciating detail”. When Parliament demanded sight of them, a highly secretive bunch of papers was eventually submitted to a limited audience – deemed by readers on all sides to be statements of the obvious. This turn of events should, at the very least, be deeply concerning.

The question here is not about the apparent (or should that be ‘alleged’) incompetence of the government in driving the negotiations for the UK’s departure from the EU, but the fact that someone up there is misleading not only Parliament, but the British public. This is not about whether or not we should be leaving the EU; this is not about whether the government is going about its work in the right way or competently; this is not about democracy, parliamentary sovereignty or the legitimate confidentiality demanded by sensitive process; this is about the normalisation of corruption (which, in terms of language, is no less serious than in other ethical matters), the easy acceptance of lying and misrepresentation by a bewildered public, and the implications for civil society (as well as what we teach our children by word and example) of allowing language to be debased, facts to be dismissed in the face of ‘alternative truths’, and for this to be done with such casual impunity.

I have lots of conversations with concerned politicians and journalists about the corruption of the political discourse. I am less sure what to do about it other than to challenge it and try to demonstrate a different way. This goes deeper than “speaking out”.

Any ideas?
