People in Wales are stocking up on food because they're concerned there may be food shortages in the event of a no-deal Brexit.

Less than half of the food we eat in Britain is produced here, while the rest comes from abroad, 30% of it from the EU according to government figures.

As Theresa May looks to get her Brexit agreement through parliament next week, the Farmers' Union of Wales (FUW) is among those concerned, warning "the disruptions in the extreme 'cliff-edge' Brexit type scenarios could well lead to shortages of certain foodstuffs in the short term until supply chains readjusted".

And a Leave-backing former cabinet minister told HuffPost UK this month that “we won’t be able to get certain foods like bananas or tomatoes but it’s not like we won’t be able to eat”.

All of that has led to some householders starting to buy in extra long-life food, although many others say there's no reason to panic.

A government spokesman told us: "People do not need to alter their eating habits or current shopping pattern.

"The UK has a high degree of food security built upon a diverse range of sources which will continue to be the case whether we leave the EU with or without a deal.”

However, Sian Richards in Cardiff says she's concerned about supply chains breaking down if there's a no-deal Brexit.

"I have some tinned goods but I am thinking more about how to replace fresh food," said Ms Richards.

"I'm thinking how long it took to get fresh bread back on the shelves after a few days of snow last March," she added.

"So, I have bought powdered milk and lots of flour, yeast etc to make my own bread. Also packets of dried soya mince as meat substitute.

"If it's all for nothing, it can go to a food bank."

She added she hoped her planning would be for nothing but, she said "I am genuinely fearful for the future and it's better for my peace of mind and my own mental health to feel well prepared".

Her views were echoed by many others on social media, including on the parenting website Mumsnet, with one user saying: "Depends on the type of Brexit we get. No deal will lead to mass shortages.

"You probably won't want to be in amongst the people angrily searching for food. Up to you. I'm not taking any chances."

Others said they were worried about prices going up, but lots of others on social media made accusations of scaremongering.

When we asked people on WalesOnline's Facebook page, most mocked the idea of stocking up.

Karen Edwards posted: "It's a load of scaremongering and its wrong to make people panic in this way. I have no more in my cupboards or freezers than I normally would."

And Paula Richards added: "We can eat other world foods, Indian, Asian and African food. These people survive here without having to visit Tesco's. We can eat what's available the same way they did during the world wars."

On January 5, Business Insider reported a research note by HSBC analyst David McCarthy detailing the concerns over food supplies, which included the high figure of food imported ("When ingredients are counted as imported, the real figure is over 80%," he wrote) and the fact that the UK's frozen food storage capacity is already full.

But writing in the Telegraph, leading Brexit advocate Boris Johnson said government warnings about shortages of food and medicines had been met with indifference from voters.

He wrote: "The grimmer the warnings, and the more systematic the efforts to make their flesh creep, the greater has been [people's] indifference and their resolve."
