If Prime Minister Theresa May is unable to win the backing of Parliament for a revised withdrawal agreement, MPs will be asked to vote on whether the UK should leave the EU without a deal instead.
For the ordinary Brit, this certainly could mean the contents of his shopping basket might change. About 30% of our food currently comes from the EU, and it is likely that some foods, such as fresh vegetables and fruit, will become more expensive in the event of no deal. Increased import taxes and transport delays could all mean a rise in prices. And if a no-deal Brexit was followed by a fall in the value of the pound, that would also have the same effect.
Supermarkets themselves have already warned that there could be empty shelves and higher prices. And Bank of England governor Mark Carney has said that, in a worst-case scenario, our shopping bills could increase by 10%.
The government has said that while a no-deal Brexit alone won't lead to food shortages, consumer behaviour could. Panic buying could mean food retailers run short of some products.
BBC.com reports that some supermarkets say they have been stockpiling some foods - but they are of course unable to do that for some fresh fruit and veg.
