Sainsbury's has reportedly delisted HRH Prince Charles' Highgrove Home Farm and Soil Association director Patrick Holden as organic vegetable suppliers.

Both Prince Charles and Holden were delisted as organic carrot suppliers for Sainsbury's at the end of January, according to reports in the Guardian.

A spokeswoman for Prince Charles told the paper that Highgrove's Home Farm had been involved in a short trial with Sainsbury's to sell organic carrots “which both sides have agreed needs more work”.

Holden added: “Supermarkets are preaching localism but it's just tokenism, their systems are still going in the opposite direction and it's disastrous.”
