LONDON (Reuters) -Oil giant BP said on Thursday it was having to temporarily close some petrol filling stations in Britain because of a lack of truck drivers, hours after a junior minister cautioned the public not to panic buy amid fears of food shortages.

Small Business Minister Paul Scully said Britain was not heading back into a 1970’s-style “winter of discontent” of strikes and power shortages amid widespread problems caused by supply chain issues.

Soaring wholesale European natural gas prices have sent shockwaves through energy, chemicals and steel producers, and strained supply chains which were already creaking due to insufficient labor and the tumult of Brexit.

After gas prices triggered a carbon dioxide shortage, Britain was forced to extend emergency state support to avert a shortage of poultry and meat.

Tesco, Britain’s biggest supermarket group, told government officials last week the dearth of truck drivers would lead to panic-buying in the run-up to Christmas if no action was taken.

Supermarket shelves of carbonated drinks and water were left empty in some places and turkey producers have warned that families could be left without their traditional turkey lunch at Christmas if the carbon dioxide shortage continues.

In a further sign of worsening supply chain dislocation, BP temporarily closed some of its 1,200 UK petrol stations due to a lack of both unleaded and diesel grades, which it blamed on driver shortages.

ExxonMobil’s Esso said a small number of its 200 Tesco Alliance retail sites had also been impacted.

“There is no need for people to go out and panic buy,” Scully told Times Radio.

“Look, this isn’t a 1970s thing at all,” he said when asked if Britain was heading back into a winter of discontent – a reference to the 1978-79 winter when inflation and industrial action left the economy in chaos.

The Bank of England said inflation would temporarily rise above 4% for the first time in a decade later this year, largely due to energy and goods prices.

A Tesco spokesperson said the group currently had good availability though it said the shortage of HGV drivers had led to “some distribution challenges.” A spokesperson for No. 2 player Sainsbury’s said “availability in some product categories may vary but alternatives are available.” Supermarkets and farmers have called on Britain to ease shortages of labor in key areas – particularly of truckers, processing and picking – which have strained the food supply chain.

LABOR CRUNCH

The trucking industry needs another 90,000 drivers to meet demand after Brexit made it harder for European workers to drive in Britain and the pandemic prevented new workers from qualifying.

“My business has about 100 HGV drivers short, and that is making it increasingly very, very difficult to service our shops,” said Richard Walker, managing director at supermarket Iceland, adding that deliveries were being cancelled.

“It is a concern and as we look to build stock as an industry, to work towards our bumper time of year, Christmas, we’re now facing this shortage at the worst possible time. I am worried.”

The National Farmers’ Union has written to Prime Minister Boris Johnson asking him to urgently introduce a new visa system to help tackle labor shortages across the supply chain.

COAL POWER?

The rise in natural gas prices is adding to the sense of chaos. Six energy suppliers have gone out of business this month, leaving nearly 1.5 million customers facing a rise in bills.

Just over a month before Johnson hosts world leaders at a United Nations climate conference, known as COP26, power generator Drax Group Plc said it could keep its coal-fired power plants operating beyond their planned closure next year.

Britain is having talks with the energy regulator Ofgem about whether or not a cap on gas and electricity prices for consumers may have to go up, Scully said.

The cap was brought in to stop energy companies gouging consumers but has now turned their businesses unprofitable as it is below the wholesale price.

Business Secretary Kwasi Kwarteng told parliament the government would not bail out failed energy companies and would not offer grants or subsidies to larger energy companies.
