Your ‘umble scribe is not a listener to Rupert Murdoch’s TalkRadio channel, being as it is top-heavy with right-wing presenters and commentators.

Furthermore, its audience compared to other national broadcasters is tiny, with Rajar figures revealing an average national number of listeners of 433,000, i.e. less than the current estimated population of Bristol.

One of those right-wing presenters had a bad day at the studio yesterday.

Step forward one Archibald Michael Graham, otherwise know as ‘Iron’ Mike, former editor of the Scottish edition of the Daily Mirror and former assistant editor of the Daily Brexit (which some still call the Express. Ed.).

Yesterday he’d invited Insulate Britain spokesperson Cameron Ford, onto the TalkRadio breakfast show, where he is currently deputising for the dreadful Julia Hartley-Brewer, ostensibly to discuss Insulate Britain’s latest protest action, but more likely so that Ford could give him a good verbal kicking for the entertainment of the station’s none too large audience.

However, matters did not progress entirely to plan, leaving Iron Mike’s carapace pitted with rust as he ended up displaying his own stupidity, which has now gone viral around the English-speaking world.

Graham’s stupidity was so egregious that the hashtag #ConcreteMike is trending on Twitter today.

The interview, which lasted less than one minute in total, starts with no style at all. Graham launches straight into an ad hominem attack on his guest – a carpenter by trade – claiming that wood is not a sustainable product, before trying to assert that concrete is a sustainable product, before being politely corrected. There then follow a period of silence before Graham ends the interview thinking he’s embarrassed his guest, whilst not having the nous to realise he has opened his mouth and inserted his foot up to the ankle, as per the video clip below.
