Theresa May made a schoolboy error marking the first anniversary of the Novichok attack

Here’s so-called prime minister Theresa May marking the first anniversary of the Salisbury Cathedral Novichok attack on Twitter.

Except as the Guardian’s Jim Waterson was keen to point out, there was an unfortunate schoolboy error.

Yep, sounds about right. And here are some of our favourite things people said about it on Twitter.

The tweet was later deleted, May’s office deciding to play it very, very safe by doing this.

At least they managed to get their own front door right, except some people weren’t letting it go (and quite right too).

For future reference …

To conclude.
