The UK could face food shortages by the summer if the Iran war continues, a worst case scenario drawn up by government officials suggests.
The closure of the Strait of Hormuz could continue to disrupt global supply chains, leading to shortages of carbon dioxide (CO2), which is used in the food and drinks industry.
A spokesperson from the Department for Environment, Food & Rural Affairs said these scenarios are planning tools, not predictions of future events.
BBC business correspondent Emma Simpson explains what this could mean for supermarket shelves.
