UK PM Starmer Says Kneecap Should Not Perform Glastonbury

"This is about the threats that shouldn't be made. I won't say too much because there's a court case on, but I don't think that's appropriate," he added.

Then why say anything at all, Keir?

It's not appropriate for him to say anything.

Partially because there's a court case, and partially because which musical acts play at a music festival are so far removed from the remit of the office of Prime Minister it's ridiculous he's commenting on it in the first place.
