The significant background that the UK just delivered a House of Lords enquiry in to the food system[0] which recommended a "complete ban" on junk food advertising and that the government ban junk food vendors from regulatory feedback. You can bet the consumer packaged goods (CPG) AKA 'junk food industry' - the likes of Mondelez, etc. - are actively resisting these changes with all manner of false reports, shoddy advertising doublespeak and back-channel arrangements. Given this background, the ban is relatively light touch. Expect further developments.
