The UK has strict laws and regulations regarding advertising and politics, as do most countries in the world.

However, you'd imagine that saving the environment is something that should be apolitical because it concerns everyone, everywhere. Sadly, this view isn't shared by the UK government office responsible for vetting television advertising, Clearcast.

Advertising can't be broadcast if it's "directed towards a political end" under the 2003 Communications Act, which they claim this advert by supermarket chain Iceland does.

Take a look.

Greenpeace originally produced the advert with Emma Thompson narrating, however Iceland offered to broadcast the advert as part of their Christmas campaign.

As Iceland's founder, Malcolm Walker, explained in a statement given to media, the advert "would have blown the John Lewis ad out of the window. It was so emotional."

Instead, a truncated 10-second clip version of the advert will run and highlight their stance on palm oil briefly.
