Brexit resurfaces as Labour leadership contenders stake competing claims

Brexit has returned to the forefront of Labour Party politics as senior figures vie for prominence in a prospective leadership battle, rekindling arguments over the the country’s connection with the European Union. Former Health Secretary Wes Streeting declared at the Progress Conference in London on Saturday that departing the European Union was “a catastrophic mistake”, whilst concurrently disclosing his bid to challenge Sir Keir Starmer for the leadership of the party. The remarks have pushed the contentious issue back into the public eye at a point at which the party has mostly attempted to sidestep revisiting the disputed topic, with other leadership contenders now forced to clarify their own stances on whether Britain could potentially return to the bloc.

Streeting’s strong position on the EU revives divisions within the party

Wes Streeting’s assertion that Brexit was a “catastrophic mistake” constitutes a substantial shift from the cautious approach pursued by Sir Keir Starmer’s government. Speaking at the Progress Conference, the previous Health Secretary contended that Labour had struggled with “overcautiousness” in opposition, being “too afraid of what the Tories might say” about divisive policy positions. He argued that the party must now confront “the big issues that define our age”, with Brexit leading his list of 3 crucial national choices needing renewed discussion and decision-making.

Streeting’s action has immediately revealed cracks across Labour’s senior ranks. His assertion that Britain’s future “lies” with Europe – and in time returning to the European Union” fundamentally questions the party’s existing approach of maintaining strict “key conditions” against rejoining the common market or trade union. However, he was mindful to note that any restoration to European Union membership would necessitate a fresh electoral mandate. The comments have put other potential leadership rivals, including Greater Manchester civic leader Andy Burnham, in the awkward position of being forced to publicly clarify their own positions on European Union relations.

• Streeting asserts Brexit has rendered Britain less wealthy and powerful from the Industrial Revolution
• Labour party hierarchy has historically steered clear of relitigating the contentious EU question of membership
• Streeting highlights any EU rejoin would necessitate a new electoral mandate beforehand
• Conservative Party Chairman Kevin Hollinrake accused Labour of diverting attention away from cost of living

The Makerfield constituency contest emerges as a Brexit battleground

The upcoming by-election in Makerfield, set for 18 June, is quickly becoming as a symbolic contest for rival perspectives on Britain’s relationship with the EU. Andy Burnham, the Greater Manchester mayor pursuing the Labour candidacy, has become trapped between the party’s cautious official stance and the increasingly direct positions being advanced by leadership hopefuls. When pressed by ITV News on whether he supports EU rejoin, Burnham conceded that “in the long-term there is a case for that” but maintained he is “not advocating that in this by-election”, reflecting the difficult political balance the party must walk.

Burnham’s equivocation emphasizes the political sensitivity concerning Brexit in local areas like Makerfield, where the Leave vote remains considerable. Should he secure both the Labour nomination and win the seat, he would be set to mount a challenge to the leadership against Sir Keir Starmer. However, his carefully calibrated remarks expose the conflict between accepting Brexit’s financial impact and upholding the democratic mandate demonstrated in the 2016 referendum—a tension that will almost certainly shape Labour’s leadership discussion.

Reform Party leverages pro-Brexit feeling

Reform UK has pinpointed Makerfield as promising territory for engaging Leave voters frustrated with Labour’s vague approach on EU relations. The party has emphasised that 65 per cent of the constituency voted for Brexit in the 2016 referendum, a considerable majority that indicates significant reservoir of support for candidates prepared to defend the Leave decision. By contrast, Labour’s reluctance to firmly advocate for Brexit or articulate a defined strategy for the post-Brexit landscape leaves an opening for populist challengers to capitalise on.

The appearance of Brexit as a campaign issue in Makerfield demonstrates broader political positioning by Reform UK to present itself as the genuine representative of Leave voters. As Labour leadership contenders deliberate on the party’s ongoing connection with Europe, Reform UK’s willingness to champion Brexit defence provides a sharp contrast narrative. This development threatens to complicate Labour’s attempts to hold the seat whilst simultaneously managing internal divisions over the party’s sustained approach to Europe.

The mayor handles the European Union issue with care

Andy Burnham’s reply to inquiries about EU rejoin exposes the unstable situation facing Labour’s prospective candidate hopefuls. The Greater Manchester civic leader, who is campaigning to become Labour’s nomination in the Makerfield contest scheduled for 18 June, conceded that “in the long-term there is a case for that” when asked about returning to the European Union. Yet he quickly qualified this by stating he is “not pushing that in this contest”, reflecting the party’s broader hesitance to openly commit to a pro-EU agenda that might estrange Leave-voting areas.

Burnham’s carefully calibrated approach reflects his past remarks made publicly regarding the 2016 referendum outcome, maintaining that any shift toward EU rejoin would demand a new mandate from voters secured through a general election. This measured stance enables him to signal openness to greater EU integration amongst left-leaning party members whilst simultaneously putting at ease Leave voters in traditional party strongholds. The juggling act underscores the electoral minefield Labour must manage as it contends with its identity following Brexit and future direction under new leadership.

• Burnham acknowledges enduring argument for EU rejoin but avoids active promotion
• Any EU rejoin would necessitate fresh electoral mandate from UK voters
• Strategic positioning aims to balance both reform-minded and pro-Leave Labour members

Conservative and Labour parties capitalise on the opportunity

The Conservative Party has acted swiftly to weaponise Streeting’s Brexit comments, with Party Chairman Kevin Hollinrake criticising Labour’s eagerness to revisit the EU question as a damaging distraction. Hollinrake contended that whilst Labour senior figures debate European policy, the government remains unable to focus on the pressing concerns of British households and enterprises, particularly the cost of living crisis and financial security. This riposte reflects the Tories’ broader strategy of portraying Labour as fixated on overturning Brexit rather than tackling pressing domestic issues. The intervention underscores how profoundly Brexit is entrenched in British political debate, capable of reigniting partisan splits at crucial moments.

Reform UK, in the meantime, has pinpointed Makerfield as promising territory to advance its pro-Brexit credentials and appeal to disaffected voters. The party has highlighted that 65 per cent of constituents supported Leave in the 2016 referendum, positioning itself as the authentic guardian of that mandate. By contrasting its unequivocal defence of Brexit with Labour’s apparent lack of commitment and the Conservatives’ difficulties in delivering, Reform UK hopes to unite those who voted Leave under its banner. This three-way contest illustrates how the EU relationship question continues to split traditional party loyalties and reshape electoral calculations across British politics.

What the comeback means for Labour’s strategic path

The rise of Brexit as a key focal point in Labour’s leadership contest indicates a fundamental reckoning within the party over its strategic approach and ideological stance. Streeting’s readiness to express what many in the party have privately thought—that leaving the EU was economically damaging—constitutes a challenge against the careful consensus Sir Keir Starmer has maintained since taking the leadership. This fracture implies Labour’s future leader may face pressure to take a clearer position on European engagement, potentially reshaping the party’s attraction for Remain-voting constituencies and younger people who regard Brexit as a defining policy failure.

However, the party confronts a tricky juggling act. Labour’s core working-class constituencies, illustrated by constituencies like Makerfield where 65 per cent voted Leave, continue to be deeply wary of any call to reverse the referendum result. Candidates like Andy Burnham must handle this challenge with care, acknowledging long-term possibilities whilst avoiding alienating Leave voters in important by-elections. The consequences of these rival leadership approaches will probably decide whether Labour tries to resolve the Brexit divide or regards it as a enduring characteristic of British politics, with profound consequences for the party’s electoral fortunes and governing agenda.
