Dover and Portsmouth Migrant Blockades Expose UK Policing Gaps as Masked Group Vows More Action

Since masked demonstrators shut down traffic to the Port of Dover on Saturday, September 5, and blocked buses carrying migrants in Portsmouth the following night, British authorities have struggled to explain how a group with weeks of public recruitment activity caught police flat-footed.

Hundreds of men, mostly dressed in black with balaclavas, chanted "stop the boats" and "Christ is king" as they linked arms across the main road into Dover, according to CNN. National Highways reported the resulting backup stretched four miles. Kent Police made no arrests and called it a "spontaneous protest."

The next night in Portsmouth, protesters first tried to stop lifeboats from bringing roughly 140 migrants ashore, then attempted to block buses taking them to a processing facility, CNN reported. Police vehicles had windscreens smashed, according to weeklyblitz. Hampshire and Isle of Wight Constabulary opened an investigation to identify anyone responsible for assaults on officers or criminal damage, but made no arrests that night either.

Both actions were claimed by Patriot Platform, a group founded in June by Daniel Thomas, known online as Danny Tommo, a former associate of anti-Islamic activist Tommy Robinson, according to CBS News. Thomas was previously jailed after pleading guilty to attempted kidnapping in 2016, CBS reported.

Thomas posted on X after Dover that participants "stuck to the plan and maintained complete discipline," adding, "A message was sent! Now imagine how powerful the next message will be." The Guardian reported that at a recruitment event in Burton Dassett last month, Thomas told supporters, according to the anti-fascism outlet Searchlight, that "in the next three or four weeks, we are going to ask you to be part of one of the biggest pushbacks this country has seen from its men since world war two."

HOPE Not Hate, which tracks far-right groups, told CNN the Portsmouth incident "shows the growing trend of anti-migrant vigilantism coming to a head in the public eye," and said Thomas has "little hope of persuading others that Patriot Platform is a safety-first community group when its members march through the streets wearing balaclavas and have been exposed for their violent criminal records."

Labour MP Mike Tapp, writing in The Mirror as cited by CBS News, said the Dover action "was clearly organized, yet Kent Police appear to have had little advance warning," and said he would ask whether intelligence was missed and whether mutual aid from forces like London's Metropolitan Police could be mobilized faster next time.

The Guardian went further, reporting that residents of a village 18 miles from Dover had tried to warn authorities on the Friday before the protest that dozens of men were gathering there, some threatening to "attack Muslims." Kent Assistant Chief Constable Nigel Brookes and Policing Minister Sarah Jones both described the events as "protest activity" when questioned by MPs. The Guardian argued this language understates an organized, uniformed mobilization it likened to intimidation tactics "not seen in Britain since the 1930s."

The Guardian and a Bluesky post from commentator Scott Horton both drew a comparison to Palestine Action, the pro-Palestinian group banned as a terrorist organization after members broke into RAF Brize Norton and sprayed paint on military aircraft. Britain recorded terror arrests at record levels for the year to March, The Guardian reported, many involving elderly Palestine Action supporters holding placards. Whether that contrast reflects a double standard in how authorities categorize political violence and property damage versus mass road-blocking intimidation is a genuine open question neither the Home Office nor Kent Police has directly addressed.

Reform UK leader Nigel Farage, while condemning the masked protesters as "disgusting" on GB News and saying "nobody in any political protest, on the left or right, should appear in balaclavas," also argued the underlying anger is legitimate. Farage said communities are "fearful for the safety of women and girls" and "even more fearful for the threats to our national security," pointing to reports of Iranian Revolutionary Guard agents attempting to enter Britain, according to Breitbart. He said a Reform government would push back Channel boats within a fortnight under an agreement with National Rally's Jordan Bardella.

That security concern is not baseless on its face: nearly 200,000 migrants have crossed the Channel since 2021, CBS News reported, and vetting of new arrivals is minimal. But weeklyblitz noted crossings are down more than 40 percent compared with the same period last year, meaning the volume driving public anger is actually shrinking even as the protest movement organizing against it grows more confrontational.

The Home Office condemned the Portsmouth events as "intimidating and thuggish behaviour" while affirming "the right to peaceful protest is fundamental to our democracy." Hampshire police's investigation into the Portsmouth assaults and property damage remains open, with no arrests announced as of this writing. Whether Kent and Hampshire police change how they monitor groups like Patriot Platform ahead of what Thomas has promised will be an even bigger mobilization remains unresolved.
