This is a rather peculiar one I admit, as it mentions her son administering Ribena to Cummings, but perhaps more importantly she states she thinks she had COVID, something Cummings at the Press Conference denied. And neglects to mention all of this happened in Durham not London.

I think we can call this one an honest error - "will remain at is London home" was at that stage a reasonable thing to say, because that is where everyone assumed he was. And, well, you know, that's where - according to the guidance - he was supposed to be.

At the Press Conference on Monday, Cummings denied that he was in Durham on that day, and said he had evidence to prove it. That evidence has not been published. So for the moment this is the Mirror's word against Cummings's.
The only other thing I have vaguely seen is a series of tweets alleging Cummings was in Durham on 11 May:

But surely that cannot be what the PM means?
There is also this:

If there is anything I am missing I am happy to add to the thread...
But the PM's case looks a little bit thin here. And
would be easy to deal with, if they wanted to.
