Thousands of pro-Brexit activists are planning to rally at Parliament Square in central London 1600-1900 March 29. The purpose of the protest is to demand the government follow through on its commitment that the UK leave the EU. Smaller groups of activists are planning to march to the rally venue via surrounding roads and will likely begin to assemble around 1330. Protesters also plan to gather on Whitehall, opposite Prime Minister Theresa May's official residence on Downing Street. A counter demonstration is planned from 1600 at the nearby Richmond Terrace.

Parliament Square, outside the UK House of Parliament, is a frequent protest venue. Protests associated with Brexit will likely be well attended. Police are likely to implement localized movement restrictions, including road closures, to facilitate the event. Traffic congestion is possible on routes through the area, including on Whitehall and the Embankment. Congestion is likely at local London Tube (underground) stations, including Charing Cross, Embankment, Saint James Park, and Westminster, as protest participants arrive and depart.

Although unlikely, low-level clashes between police and protesters, or between rival activists, cannot be completely ruled out, particularly if participants become rowdy or attempt to block local routes, including Westminster Bridge. Clashes would poses an incidental physical threat to bystanders. Smaller protests are likely in other UK cities but are unlikely to prompt significant disruptions.


Background and Analysis

The protests will coincide with a parliamentary vote on the prime minister's withdrawal agreement from the EU and will take place on the day when the UK was originally scheduled to depart the bloc. Parliament's previous rejection of the agreement prompted the government to request a delay for the UK's departure. If Parliament passes the withdrawal agreement, the UK is scheduled to leave the bloc May 22; if the agreement is again rejected, the UK is scheduled to leave April 12 with neither a deal nor a post-EU transitional period in place. Further protests by both pro- and anti-Brexit activists are likely around the country until the UK formally leaves the EU.



Avoid Parliament Square on the afternoon of March 29 to mitigate related disruptions and as a routine security precaution. Allow additional time for travel in Westminster on the afternoon and evening of March 29. Leave the area immediately at the first sign of a confrontation.

March 27: Anti-Brexit activists to demonstrate at UK-Ireland border crossing and in Dublin, March 30. Expect localized transport disruptions.

This alert began 28 Mar 2019 19:06 GMT and is scheduled to expire 30 Mar 2019 23:59 GMT.

  • Event: Protests
  • Location: UK-Ireland border crossings; Dublin
  • Start Time/Date: 1500 March 30
  • Impact: Heightened security; localized transport disruptions



The civil society group Border Communities Against Brexit (BCAB) has organized protests along the UK-Republic of Ireland border and in Dublin from 1500 March 30. The purpose of the demonstrations is to protest the possible negative impact Brexit may have on cross-border movement. Protesters will gather at the following border locations:

  • Blacklion/Belcoo
  • Bridgend/Londonderry
  • Carrickarnon
  • Lifford Bridge
  • Moybridge/Aughnacloy


Activists will also stage a related demonstration at the Croke Park Stadium in Dublin from 1400.

Authorities will likely deploy a heightened security presence to monitor and facilitate the demonstrations. Large numbers of people and associated crowd-control measures, such as movement restrictions, may lead to localized disturbances. Protesters may also attempt to block nearby roads, resulting in transport disruptions. Although no groups have announced specific plans to do so, pro-Brexit activists could hold counterprotests. While the events will likely remain peaceful, isolated skirmishes between police and protesters cannot be ruled out.



Avoid the protests as a standard security precaution and to mitigate associated disruptions. Leave the area at the first sign of a confrontation. Allow extra time for transiting any UK-Ireland border crossings on March 30.

March 21: Pro-Brexit activists threaten go-slow protests on major UK highways from March 22. Traffic congestion and transport delays possible.

Activists from the Brexit Protest and Direct Action Group UK have threatened to stage a series of go-slow convoys around the UK starting March 22 to denounce the government's intention to defer the country's Article 50 withdrawal from the EU beyond March 29. Members of the group are planning actions on the following routes:

  • March 22: M-1, M-4, and M-5 motorways.
  • March 23: M-62 and M-25 motorways.

Organizers have also threatened to hold similar actions on the M-6, M-42, M-55, and M-61, and the A-1, A-55, and A-66 routes. Further such protests are likely on these and other major routes ahead of and on March 29, particularly if the EU approves the UK government's request to grant an Article 50 extension. It is currently unclear how disruptive the protests will be. Organizers state that their vehicles will drive at a maximum of 40 mph (64 kph), so any traffic delays are unlikely to be crippling. Nevertheless, heavier than normal traffic is likely on affected roads, particularly on the M-25 London Orbital. Organizers have stressed that the events will be peaceful; participating vehicles will be accompanied by a police escort and the convoys will likely occur without incident.



Check the status of major routes in England and Wales before conducting intercity road travel March 22-23. Anticipate possible short-notice disruptions ahead of March 29 and allow additional time for road travel. Consider alternative means of transport, including rail options.
