An Irish freight group has warned of huge post-Brexit disruption to supply chains in coming weeks as the impact of Britain leaving the EU takes hold.
The Freight Transport Association of Ireland (FTAI) wrote to Taoiseach Micheál Martin, warning him of empty supermarket shelves, job losses and rising prices unless the Government takes action to help the industry bring goods into the country.
The letter, signed by FTAI general manager Aidan Flynn, said the industry was struggling to keep the flow of goods moving.
"There is a growing backlog of goods of all hues, from mechanical parts (car parts) to electrical household goods, furniture, clothing, food supplies, sitting in depots because there are not enough agents to process the declarations correctly," the group said.
"There are issues with the systems and there are problems with providing enough support and guidance on the new requirements to industry to make this work.
"The net result will be that companies operating on very tight margins will cease trading, creating unemployment, supply lines will disappear and the consumer will be left with less supply and increased prices."
The association said stockpiling before Christmas had masked some of the effects of Brexit so far.
Mr Martin said the Government and businesses are managing very damaging developments in the wake of Brexit.
He said these include considerable change and greater complexity, especially anyone doing business with Great Britain.
The Taoiseach said the agreement reached between the EU and the UK on Christmas Eve was the "least bad" version of Brexit.
