I'm not convinced by the idea that the papers have a "duty" to report the situation to the general public. The Mirror and the Guardian would have co-operated over this story for the political impact it was likely to have. Since two months had already gone by, suppose that they'd held off for a year and then published it. Then it wouldn't have any impact on the lockdown (I'm assuming we're out of that by then!). I do think that the most important issue right now is maintaining effective steps to control this virus, and in that context we definitely could have managed without knowing about Cummings's trip. At least, I could have managed, but there are some who, like the Mirror and the Guardian, attach a greater importance to embarrassing the government. Incidentally, if he didn't make the decision "off his own back", but consulted Boris before he went, that would jeopardise the integrity of the government much more, and I expect the Mirror and the Guardian are working on that.
