Upper Bann MP Carla Lockhart has resigned from the Democratic Unionist Party following a bitter dispute over the party’s handling of the Drumcree parading controversy. Lockhart announced that she was leaving the DUP on a point of principle and confirmed she will continue to serve in the House of Commons as an independent unionist.
The political fallout stems from widespread unionist anger surrounding Sinn Féin’s involvement in demonstrations along the Garvaghy Road in Portadown, County Armagh. The protests successfully blocked a contentious Orange Order parade from proceeding down the predominantly nationalist street. First Minister Michelle O’Neill and several other senior Sinn Féin figures have subsequently been interviewed by police investigating the demonstrations, with unionist critics accusing the party of unlawful conduct.
In response to the demonstrations, the DUP—which governs in power-sharing with Sinn Féin in Northern Ireland’s devolved administration—announced it would block official engagements involving O’Neill. However, Lockhart argued that this measure was insufficient. She had publicly demanded that party leadership withdraw Stormont’s deputy first minister to force O’Neill out of their joint office entirely, arguing that any graduated response would insult constituents who trusted the party.
Sinn Féin vice-president O’Neill has defended her participation in the protests, maintaining that her presence was the right course of action. DUP leader Gavin Robinson ultimately stopped short of Lockhart’s demand to collapse the executive office, retaining the support of the DUP officer and assembly teams while avoiding the risk of being blamed for failing to secure a budget or triggering further disputes, such as nurses’ pay strikes.
In a statement posted to her Facebook page on Monday, Lockhart emphasized that her primary responsibility remains with her constituents in Upper Bann. She described her departure as a sad and deeply personal decision, noting that she could not stand idly by while Sinn Féin ignored the rule of law and promised consequences failed to materialize. Lockhart added that she looks forward to collaborating with all shades of unionism to advance their shared political causes.
The DUP expressed regret over Lockhart’s departure, acknowledging her service to the constituents of Upper Bann while asserting that the only beneficiary of divisions within unionism is Sinn Féin. The party stated that while it shares the widespread unionist anger over O’Neill’s actions, its disagreement with Lockhart centered entirely on the most effective strategy to secure accountability and serve Northern Ireland.
The resignation drew swift reaction from other unionist figures. Traditional Unionist Voice leader Jim Allister offered his congratulations, drawing parallels to his own departure from the DUP two decades prior and arguing that the leadership’s refusal to act demonstrated a preference for keeping O’Neill in office.
Political analysts noted that Lockhart had been on a collision course with party leadership for weeks. Despite having backing from Portadown Orangemen and regional unionists, she became increasingly isolated within the parliamentary ranks as Robinson maintained solid backing from the party’s assembly team. The departure reduces the DUP’s representation in Westminster to just four MPs—down from a previous high of ten—compounding a bruising period for the party as it prepares for assembly elections scheduled in seven months.
