Dominic Cummings cannot stop talking. It’s interesting stuff, up to a point. Lynn Barber interviews him in this week’s edition of The Spectator, the magazine where Cummings’ wife, Mary Wakefield, is commissioning editor.

Again, the ex-SpAd-in-chief makes some extraordinary allegations about Boris Johnson’s inner circle, particularly his wife Carrie Symonds. Cummings describes her as “crazy”. He says he tried to push her into a “job with lots of foreign travel”, such as getting the Cabinet secretary to give her a job on COP26, traveling round with Kate Middleton.

Cummings also claims he was in line to receive a peerage when he left office last autumn, with Boris branding himself “king” of “chaos” inside Government.

His interview comes less than a month after his intense, long conversation with the BBC’s Laura Kuenssberg in which he said that he tried to oust Boris from the premiership following the 2019 election.

All these “Domshells” are damning, to say the least. From his revealing Select Committee appearance to his daily Twitter tirades, Cummings is eager to torpedo his old boss – and indeed the rest of the Westminster establishment – whatever the price.

But in making these constant interventions, are people beginning to tire of Cummings’ constant goings? A YouGov poll from May found that only one in 7 of the British public trusted Dom to tell the truth about the Government’s handling of the coronavirus pandemic.

“He needs to slow down, there’s too much of it,” a former supporter texts.

Cummings often dismisses journalists and pundits as idiots. But media is hard. There’s a shelf life to these things, and sometimes less is more. The value of these attacks diminishes with their frequency.
