Sainsbury's issue alarm over fresh fruit and vegetable shortages 'within days'

The supermarket giant said France’s ban on freight hauliers from the UK could affect food supplies but assured customers that crucial Christmas dinner supplies are available and already in the country.

Transport Secretary Grant Shapps said the ban on accompanied freight was “slightly surprising”.

Thousands of lorries that were meant to travel across the English Channel on Monday have been told to stay away from Kent ports.

HGVs turning up at Dover this morning have been greeted with glowing signs saying “French borders closed” and are being turned away.

It comes as the south-east of England grapples with a new variant of coronavirus that could be up to 70 per cent more transmissible than the original strain.

A Sainsbury’s spokesperson said: “All products for the Great British Christmas lunch are already in the country and we have plenty of these.

“If nothing changes, we will start to see gaps over the coming days on lettuce, some salad leaves, cauliflowers, broccoli and citrus fruit – all of which are imported from the continent at this time of year.”

Transport Secretary Grant Shapps said that “probably about 20 per cent” of goods going into and out of the country passes through Kent.

He told Sky News: “But it’s not the mainstay. Most goods actually come in and out by unaccompanied containers and those will continue to flow.”

Asked about what the shortages could be, Mr Shapps said: “Obviously we don’t want these links to be closed for too long, but it’s not unusual for them to be closed and disrupted.

“In the short term it’s not a specific problem. But of course the key is to get it resolved.”

While unaccompanied freight is exempt from the 48-hour ban, goods that would usually be transported on lorries driven onto ferries by drivers face being unable to cross the Channel to France.

This will mean that the vast majority of trade out of the port of Dover could be held up at the border.
