She's an excellent in-depth feature writer but never usually called on for everyday court reporting or hard news. I wonder if she is digging deeper on the subject? That would be something.
Yes, I wondered this. Court reporting is pretty specialist and they usually use dedicated court reporters for it. So either she's switched roles in the Guardian or, quite possibly, as you say, she's digging deeper, which would be fantastic. She is a superb journalist. I would be surprised if the Guardian is letting her investigate, but stranger things have happened, I suppose.
And as titchy says, she is married to Jo Johnson, Boris's brother and former government minister. She even wrote about the height of the Windrush scandal, where she would do a media interview to talk about how terrible the government was, and then her husband would do an interview defending the government. Weird.
