Carla Lockhart quits the DUP over its response to the Drumcree dispute

Carla Lockhart, the Member of Parliament for Upper Bann, resigned from the Democratic Unionist Party (DUP) on the evening of November 2. She said its response to the Drumcree parade dispute had "fallen far short of the profound consequences promised." She will sit in the House of Commons as an independent unionist. Her departure leaves the DUP with four MPs at Westminster, down from 10 in 2017, the Irish Times reported.

The split is over how unionists should respond to First Minister Michelle O'Neill of Sinn Féin taking part in a protest on the Garvaghy Road in Portadown, County Armagh, in October. That protest blocked an Orange Order parade that the Parades Commission had allowed for the first time in 28 years. Lockhart wanted the DUP to withdraw Deputy First Minister Emma Little-Pengelly from office, a step that would automatically remove O'Neill too and stop Northern Ireland's power-sharing Executive from functioning. The DUP leadership under Gavin Robinson chose instead what Lockhart called a "graduated response": a boycott of joint engagements with O'Neill, while keeping the institutions running.

The resignation comes about seven months before the next Northern Ireland Assembly election, due in May 2027. The DUP also faces competition for unionist votes from Traditional Unionist Voice (TUV) and the Ulster Unionist Party (UUP). This article sets out what Lockhart said, how the parties responded, the background to the dispute and what the polling shows.

What Lockhart said

Lockhart posted her resignation letter to Robinson on social media on Monday evening. "It is with deep regret that [I] resign from the DUP Parliamentary group and my membership of the party with immediate effect," she wrote, according to RTÉ. "The DUP has been my political home for more than two decades. This is a painful decision, reached after much reflection."

She said her letter to colleagues of October 29 had set out "the steps I believed necessary." She added: "The party's response has fallen far short of the profound consequences promised. Alongside my concerns over the implementation of the Irish Sea border, this has left me unable, in all conscience, to continue within the party."

The letter was conciliatory in tone. "None of this is personal, and I bear no animosity towards you or the party," she wrote. She added that she stood "ready to do so in friendship and cooperation" on shared aims for Northern Ireland and the Union.

In a separate statement, Lockhart said she was leaving "on a point of principle" and that she "cannot stand idly by" while, in her view, Sinn Féin ignores the rule of law, the BBC reported. She said she would "look forward to working with all shades of unionism, elected or not, to advance the cause we love." According to The Journal, she said she is "not starting a new political party" but wants to help build a "grassroots movement" within unionism. She published an eight-page "Renewed Vision for Unionism" alongside her letter, the Irish Times reported.

Lockhart has said she will stand again. "At the next Westminster election, rest assured the name Carla Lockhart will be on the ballot paper," she said in a statement quoted by Belfast Live. She won Upper Bann in 2024 with a majority of more than 7,000 over Sinn Féin.

Her break with the party had been building for weeks. About 10 days before quitting, she resigned as a DUP party officer over its strategy, the Irish Times said. At a rally in Portadown last month she demanded O'Neill's resignation, borrowing a line from Margaret Thatcher: "Michelle O'Neill must go. That's where I stand and this lady's not for turning." In her October open letter, she called removing the deputy first minister the "only one credible option" and said a graduated response would be "insulting to those who have trusted us."

How the DUP responded

The DUP said it regretted her decision. "The only winner out of further divisions within unionism is Sinn Féin," a spokesperson said. "We share the anger felt across unionism at Michelle O'Neill's actions. Our disagreement is over the course of action that will secure accountability and best serve Northern Ireland."

Speaking to reporters at Parliament Buildings before the resignation, Robinson said collapsing the Executive was not the right response. "It cannot be that every time a lawmaker in Northern Ireland breaks the law, that the answer is to bring down the institutions," he said, according to Belfast Live. He said he was sorry Lockhart disagreed with the majority view in the party.

On October 29, the DUP announced that Little-Pengelly would no longer take part in joint public engagements with O'Neill. She would also not give permission for O'Neill to carry out engagements alone in the role of first minister, RTÉ reported. Because the two offices are joint, many official duties need both holders to agree. The boycott includes Remembrance Sunday ceremonies on November 8, the Irish Times reported.

The BBC's Northern Ireland political staff noted that Robinson had the support of the party's officers and Assembly team. Collapsing the Executive without an agreed budget, and during a public sector pay dispute, was a risk he was not willing to take, they wrote. That is the BBC's analysis, not a statement from the party.

Reactions from other parties

TUV leader Jim Allister, who left the DUP almost 20 years ago, congratulated Lockhart. "But for honest politicians principle matters more than position," he said. "The DUP's preference for 'O'Neill Must Stay' caused them to choose Michelle O'Neill over Carla Lockhart. Little wonder their electoral base is deserting them." He said he looked forward "to working closely with Carla" and called it "a hopeful day for unionism," the BBC reported.

O'Neill, speaking to the Assembly before the resignation, said she would "not be deterred" from doing her job and accused the DUP of a "supremacist" approach to nationalists. "At the core of it all is the DUP's inability to comprehend a nationalist First Minister," she said, according to Belfast Live. She accused the DUP of "desperately trying to turn back the clock and to undermine democracy." O'Neill has defended joining the protest as "the right thing to do," the BBC reported.

Separately, DUP Assembly member Jonathan Buckley wrote an open letter at the weekend calling on unionist leaders to discuss closer electoral cooperation before the Assembly election. UUP leader Jon Burrows indicated he was willing to engage, while Allister said the letter was motivated by DUP self-interest, Belfast Live reported.

Background: the 2026 Drumcree dispute

Drumcree has been a flashpoint since the 1990s, when Orangemen and police clashed over the lodge's wish to walk home from Drumcree church along the mainly nationalist Garvaghy Road. Successive bans kept the parade off the road for 28 years.

In late September 2026, the Parades Commission ruled that a small, restricted parade could use the route, the Guardian reported. The lodge was permitted to bring 35 members along the road in an early morning silent march, according to RTÉ. Thousands of residents and supporters, including Sinn Féin leaders, gathered on the road, and police decided they could not safely let the parade through. After a 13-day standoff, Northern Ireland Secretary Chris Bryant banned the parade on October 9, saying it was "not in the public interest." He acted on the advice of Police Service of Northern Ireland (PSNI) Chief Constable Jon Boutcher, who said the parade "would carry an unacceptable risk of serious injury, disorder and a wider contagion effect."

On October 28, the High Court in Belfast ruled the ban lawful. Mr Justice Scoffield said the decision was within the "margin of discretion" open to Bryant, but warned that those who opposed the parade "should, in my view, take no particular joy in the outcome." He said the position had been reached "at very significant cost to the people of Northern Ireland." Jamie Bryson, a legal adviser to the Orange Order's Portadown district, said the lodge would "in all likelihood" appeal.

The PSNI is investigating the protest. Assistant Chief Constable Davy Beck said in a police statement that officers had built evidential packages on 60 identified suspects, of whom 18 had been interviewed. Files are being prepared for the Public Prosecution Service. O'Neill and several Sinn Féin colleagues have been interviewed voluntarily. No charges have been announced, and no court has found that O'Neill broke the law.

What the polling shows

The most recent published poll we found on the dispute was carried out by More in Common, which surveyed 1,019 adults in Northern Ireland online after Bryant's October 9 ban, RTÉ reported. The exact field dates were not given in the published reports. For a random sample of that size the margin of error would be about plus or minus 3 percentage points. Online panel polls are weighted to approximate that, and subgroup figures are less precise.

Party	July 2026	October 2026
Sinn Féin	25%	30%
DUP	17%	18%
UUP	13%	13%
TUV	12%	11%
Alliance	11%	9%
SDLP	9%	9%

In that poll, 53% said Bryant was right to ban the parade, including 91% of Sinn Féin voters and 81% of Alliance voters. Most unionist voters disagreed: 85% of TUV voters, 76% of DUP voters and 55% of UUP voters said the ban was wrong. Among Protestants overall, 54% said it was wrong and 28% said it was right. On the question at the heart of Lockhart's resignation, 49% said Drumcree is not a strong enough reason for any party to pull out of the Executive, while 27% said it is.

The poll was taken before the DUP's boycott announcement and before Lockhart quit, so it does not measure reaction to either.

What it means and what to watch

Lockhart's move reduces the DUP's Westminster group to four MPs, alongside Robinson in Belfast East. It does not change the balance at Stormont, where she has no seat, and it does not by itself threaten the Executive. Whether more DUP members follow her, and whether she aligns with the TUV or stays independent, will shape the unionist contest for the 2027 Assembly election.

The DUP's boycott of joint engagements continues, with Remembrance Sunday on November 8 the next visible test. The PSNI investigation could lead to prosecution decisions on some of the 60 suspects. The Orange Order may appeal the High Court ruling. And the UK-EU agreement on food checks, whose text was settled on November 3, touches directly on the Irish Sea border that Lockhart cited in her letter.

Differing perspectives

How should unionist parties respond to First Minister Michelle O'Neill's part in the Garvaghy Road protest?

Each position is summarized as its supporters make it, with equal weight and in alphabetical order. A summary is not an endorsement; the evidence for each is weighed in the story above.

• Keep Stormont running and boycott joint engagements

  Who holds it: The DUP leadership under Gavin Robinson

  The DUP says it shares unionist anger at O'Neill's actions but disagrees with Lockhart about the course that will secure accountability and best serve Northern Ireland. Rather than collapse Stormont, Robinson opted for a graduated response: the deputy first minister no longer takes part in joint public appearances or official events with O'Neill, including Remembrance ceremonies. The party warns that further division within unionism benefits only Sinn Féin.

• Remove the first minister by withdrawing the deputy first minister

  Who holds it: Carla Lockhart, now an independent unionist MP, with support from TUV leader Jim Allister

  Lockhart argues that O'Neill's part in the Garvaghy Road protest means she should be forced from office, and that withdrawing the deputy first minister was the only credible option. She says any graduated response is insulting to those who trusted the DUP, and that she cannot stand by while promised consequences fail to happen. Allister says the DUP chose to keep O'Neill in office rather than keep Lockhart, and that principle should matter more than position.

• The DUP's boycott undermines democracy

  Who holds it: Michelle O'Neill and Sinn Féin

  O'Neill says she will not be deterred from doing her job as first minister by the DUP's move to block her public engagements. She argues the boycott reflects the DUP's inability to accept a nationalist first minister and a supremacist approach to nationalists, and accuses the party of desperately trying to turn back the clock and undermine democracy.
