A large group of protesters wearing black clothing and balaclavas blocked roads around Dover's seafront and port on the morning of 5 September 2026, prompting Kent Police to declare a public order incident and engage with those involved. The group is believed to be far-right demonstrators protesting against small boat crossings, and their action has halted traffic in and out of the Port of Dover, disrupting ferry services and causing significant delays for travellers.

P&O Ferries said it would rebook affected passengers onto the next available sailing if they missed their scheduled crossing. Witnesses reported the protesters arrived at around 6.45am and blocked every entrance and exit to the port area, including Jubilee Way, with unconfirmed estimates online suggesting the crowd could number as many as 300 people. Kent Police confirmed awareness of the protest but had not yet provided further detail, and the situation remained ongoing as a developing story.
