It's the Online Safety Act 2023 and was going through parliament from 2019, I'm sure the moment it becomes sufficiently unpopular in the wider public we'll see the "2023" part gain more prominence. Starmer won't be able to say it's a bad idea, because he and his party have been supportive of it since, but there'll be the usual political maneuverings. I can't see people switching to vote Green because they suggested a digital bill of rights.
