Tractors are lining up on roads outside Dover as farmers plan to block routes around the town
Kent Police said they were currently responding to an incident of “slow-moving vehicles” in Jubilee Way, one of the main roads heading to the port.
Officers are working with the Port of Dover Police on this matter, police said.
One farmer said on social media he was protesting over food trade deals.
He said supermarkets were selling British produce at “cheaper than the cost of production”, adding farmers would be taking their tractors to the Port of Dover on Friday evening.
The protest follows similar demos in France in recent weeks which saw French farmers move tractors to blockade routes into Paris, arguing they had been hit by falling incomes, environmental regulations, rising red tape and competition from imports.
