There are about 13,800 border crossings every day between the Republic and Northern Ireland. To highlight the importance of free-flowing movement, more than 150 lorry drivers have staged a protest at the Irish border.
Truck drivers taking part said they want to show how the free movement of freight is vital to businesses and trade.
The protest was brought to a standstill at the main border route, as hundreds of drivers and their supporters turned out to “show the world” what custom checks and infrastructure would look like.
George Mills, from the Irish Road Haulage Association, said: “We don’t have to fill out any documentation or electronics or otherwise to cross this border, which we need to do every day of the week because of where we live. We can’t go anywhere without crossing the border, even to do our business with Dublin."
He went to to comment: “The people of the UK don’t seem to regard the border as important. Only 2% of their trade crosses this border, but it’s nearly 100% of our trade that has to cross this border, so it’s a big concern to us. We don’t want to go back to any form of regulation that impacts that form of free movement of traffic."
