I learnt about it from the BBC News homepage, where it currently remains, but I know they show different front page stories based on location.
But yes, it's a nasty bit of overreach. What's annoying is all the people I see being vocal about it on Twitter are the alt-right or pro-Tory/Telegraph/Mail folks I wouldn't usually want to align with. I suspect the presence of Brand is key to them, and if a similar letter had been written targeting someone on the left, they would be quiet.

The author of the letter, Dame Dinenage, is a Tory MP. To my mind, the letter is quite mild; there are no threats or demands, just questions. In view of her job as Chair of the Culture, Media and Sport committee, it seems a reasonable letter to write (even on House of Commons notepaper).
