Britain could face shortage of wine and spirits at Christmas, a drinks trade body has warned.
In a letter to Transport Secretary Grant Shapps, the Wine and Spirit Trade Association (WSTA) said rising costs and supply chain chaos have held up deliveries.
Imports were now taking up to five times longer than a year ago, it said.
The government said: "We do not expect disruption to the supply of alcohol this Christmas".
The letter was co-signed by 49 firms, including Pernod Ricard, Mo?t Hennessy and the Wine Society.
It said the sector has been badly affected by the HGV driver shortage crisis, which the industry has blamed on factors including Covid and Brexit.
The letter said drinks businesses were still struggling, and further action was needed, particularly in the run up to Christmas - "a critical trading period for our sector".
"Unless urgent action is taken, we will fall deeper into delivery chaos," it added.
"Businesses like ours previously able to fulfil orders in two to three days now have to operate on a day one for day fifteen basis," the letter said.
In addition, businesses are reporting increased costs of around 7% - and often more - by freight forwarders to account for driver retention.
"This is particularly a concern for SMEs [small and medium sized enterprises] who are unable to compete with large businesses to attract drivers."
It said drivers and vehicles were "increasingly unpredictable" in their arrival times, which meant goods being either not ready or left waiting for collection.
It warned that being unable to fulfil orders on time would mean lost business and could ultimately lead to increased costs for consumers.
"Government needs to be doing all it can to ensure British business is not operating with one hand tied behind its back over the festive season and beyond," said Miles Beale, WSTA chief executive.
The WSTA called for the temporary visa scheme for HGV drivers to be extended for a year.
It also wants the government to act to help smooth congested freight routes from ports, and to provide more regular updates on how many HGV driver licences are being processed by the Driver and Vehicle Licensing Agency.
A government spokesperson said: "The UK has a strong food supply chain and we do not expect disruption to the supply of alcohol this Christmas.
"The government acted quickly to tackle the challenges to our supply chains, which were brought on by global pressures including the pandemic and the international shortage of HGV drivers."
It has invested ￡32.5m in roadside facilities for hauliers, put ￡17m into creating new HGV skills bootcamps, and launched a review of training, the spokesperson said.
"These measures are working, cutting the backlog through a huge increase in vocational licences issued and HGV tests conducted compared to before the pandemic, and there is now spare capacity in the testing system."
The warning from the drinks industry comes as food distributors warned MPs that consumers could face less food choice this Christmas because of supply chain issues.
Shane Brennan, head of the Cold Chain Federation, said suppliers were scaling back plans to ensure they can deliver.
The Cold Chain Federation represents firms involved in the storage and distribution of chilled and frozen products, including food.
"It's about reducing the amount of goods you're expected to put on the shelves," Mr Brennan said.
He made the comments on Wednesday morning to the Transport Select Committee inquiry into the road freight supply chain.
"We are very good at piling high and selling it cheap at Christmas time," he said.
"What we're having to do is strategically scale that back, in order to basically meet the promise that there will be the stuff you expect to see on the shelves, but not necessarily all the extras."
Mr Brennan said the unpredictability of the past two years had made it the toughest period in members' memories, adding that there was a lot of tiredness in the industry and problems with retention.
The supply chain is facing a number of pressures, such as drivers leaving the industry and difficulties recruiting new ones, border issues and delays with the movement of shipping containers.
Global shipping supplies are in "an unprecedented period of stress", Mr Brennan told the committee.
He said it was taking two or three days for fresh food arriving at UK ports to be delivered to stores, whereas this would normally happen on a same day or next day basis.
For frozen food, the timescale has increased from between one and three days to up to five and six days.
"We're seeing significant changes and having to re-plan on that basis," Mr Brennan said.
In September, Food and Drink Federation (FDF) boss Ian Wright warned that the UK was in for permanent food shortages.
He said: "The UK shopper and consumer could have previously expected just about any product they want to be on the [supermarket] shelf or in the restaurant all the time.
"That's over. And I don't think it's coming back."
According to the FDF, the food and drink industry is short of about half a million workers - or one in eight of the total workforce - which is leading to supply chain issues.
Several companies including supermarkets, pubs and restaurants have blamed a lack of heavy goods vehicle (HGV) lorry drivers for causing problems in their supply chains, including shortages of some products.
Lorry driver shortages have also been blamed on EU workers leaving the UK following Brexit as well as during the pandemic and tax changes making it more expensive for drivers from elsewhere in Europe to work or be employed in the UK.
Elizabeth de Jong, the director of policy at freight and haulage trade association Logistics UK, highlighted a lack of available lorry parking facilities as a key reason putting people off driving jobs.
She told the Transport Select Committee there had been evidence for years that there were far too few parking spaces, with people having to stay in their cabs at side of the road or on industrial estates, with no hygiene facilities.
Duncan Buchanan, policy director at the Road Haulage Association, told the committee that many people loved lorry driving, but it was often it was the conditions that made them leave.
However, Mr Buchanan added that the extent of the lorry driver shortage has started to ease.
"We are seeing improved throughput in tests. We had tests suspended. Since April there's been a real uptick in the throughput of people undertaking and passing tests.
"We reckon the shortage has probably fallen by about 15,000. Much of that is to do with improved test performance and improved retention. And these things when you talk about the driver shortage, everything is estimates based on intelligence we get, hard numbers are very difficult.
"But our estimate is we've come back 15,000. And that's substantial, over 6 months."
