The green entrepreneur, who has donated more than £5m to Labour, says vegan meals are healthier and better for the environment.

He is campaigning for an end to all farming of animals, which he says is now the biggest driver of the climate crisis.

He told a fringe meeting at Labour's conference that his company, Devil's Kitchen, already supplies vegan food to "one in four" primary schools.

He denied he was against farmers, insisting that he did not want to kill the industry but allow it to be "reborn".

"[Farmers] have to be part of the move to net zero, they have to move away from animal agriculture, we know that the science tells us that - and they already grow grass to feed to animals."

One regrettable side effect of the fact that children cannot vote is stuff like this.

Imagine how British adults would react if someone proposed a law banning their meat consumption.

But kids can't do anything about it -- other people choose what food is available to them in cafeterias, so...

EDIT: Maybe the real answer is to convert school cafeterias into food courts and have different caterers compete for lunch tickets or something, so that kids have a say.

The only kind of remote analog I can think of that adults tolerate is during wartime, when soldiers are drafted, so that their presence at an institution is required and someone else determines what food they will have available at that institution, if they're deployed and being issued rations.
