Shortages of some fruit and vegetables in supermarkets could be "the tip of the iceberg", the National Farmers' Union has warned.
NFU deputy president Tom Bradshaw said a reliance on imports has left the UK vulnerable to "shock weather events". Soaring energy bills exacerbated by the war in Ukraine have also put off some UK vegetable growers, he added.
He said the UK has now "hit a tipping point" and needs to "take command of the food we produce" amid "volatility around the world" caused by the war in Europe and climate change. It comes as the shortage of tomatoes in UK supermarkets has widened to other fruit and vegetables due to a combination of bad weather and transport problems in Africa and Europe.

Mr Bradshaw told Times Radio on Saturday: "We've been warning about this moment for the past year. The tragic events in Ukraine have driven inflation, particularly energy inflation to levels that we haven't seen before.
"There's a lack of confidence from the growers that they're going to get the returns that justify planting their glasshouses, and at the moment we've got a lot of glasshouses that would be growing the tomatoes, peppers, cucumbers, aubergine that are sitting there empty because they simply couldn't take the risk to plant them with the crops, not thinking they'd get the returns from the marketplace.
"And with them being completely reliant on imports - we'd always have some imports - but we've been completely reliant on imports (now). And when there's been some shock weather events in Morocco and Spain, it's meant that we've had these shortages.
"It's really interesting that before Brexit we didn't used to source anything, or very little, from Morocco but we've been forced to go further afield and now these climatic shocks becoming more prevalent have had a real impact on the food available on our shelves today."
On Wednesday, Tesco followed Aldi, Asda and Morrisons in introducing customer limits on certain fresh produce as shortages left supermarket shelves bare. Tesco and Aldi are limiting customers to three units of tomatoes, peppers and cucumbers as a precautionary measure, while Asda is also limiting customers on lettuce, salad bags, broccoli, cauliflower and raspberries and Morrisons has set a limit of two items per customer across tomatoes, cucumbers, lettuce and peppers.
Retailers believe the problems stem from poor yields on the continent and north Africa, and that supplies will improve in the coming days or weeks.
