Brexit resurfaces as Labour leadership contenders stake competing claims

Brexit has re-emerged as a focal point of Labour Party politics as senior figures compete for advantage in a prospective leadership battle, rekindling arguments over the the country’s connection with the European Union. Former Health Secretary Wes Streeting stated at the Progress Conference in London on Saturday that leaving the EU was “a catastrophic mistake”, whilst concurrently disclosing his intention to challenge Sir Keir Starmer for the party leadership. The remarks have thrust the contentious issue back into the centre of attention at a time when the party has mostly attempted to sidestep rehashing the contentious debate, with other leadership hopefuls now required to set out their own views regarding whether Britain might eventually rejoin the bloc.

Streeting’s decisive position on the EU revives party divisions

Wes Streeting’s declaration that Brexit was a “catastrophic mistake” represents a substantial shift from the cautious approach pursued by Sir Keir Starmer’s administration. Presenting at the Progress Conference, the previous Health Secretary maintained that Labour had struggled with “overcautiousness” in opposition, being “too afraid of what the Tories might say” about divisive policy matters. He contended that the party needs to confront “the big issues that define our age”, with Brexit leading his list of three essential national choices requiring new consideration and decision-making.

Streeting’s intervention has at once highlighted divisions across Labour’s senior ranks. His statement that Britain’s prospects “rests” with Europe – and eventually back in the European Union” openly contradicts the party’s existing approach of maintaining firm “red lines” against returning to the single market or customs union. However, he was careful to stress that any return to EU membership would demand a fresh electoral mandate. The remarks have placed other potential leadership contenders, including Greater Manchester mayor Andy Burnham, in the awkward position of being forced to openly explain their own positions on relations with Europe.

• Streeting argues Brexit has rendered Britain less wealthy and powerful since the Industrial Revolution
• Labour leadership has historically avoided rehashing the divisive EU question of membership
• Streeting emphasises any EU rejoin would necessitate a new electoral mandate beforehand
• Conservative Party Chairman Kevin Hollinrake criticised Labour of distraction from cost of living

The Makerfield constituency contest becomes a Brexit battleground

The forthcoming by-election in Makerfield, scheduled for 18 June, is quickly becoming as a proxy battleground for competing visions on Britain’s EU relationship. Andy Burnham, the Greater Manchester mayor pursuing the Labour candidacy, has become trapped between the party’s official cautious position and the more forthright positions being staked out by aspiring leaders. When pressed by ITV News on whether he favours EU rejoin, Burnham acknowledged that “in the long-term there is a case for that” but maintained he is “not advocating that in this by-election”, reflecting the delicate political tightrope the party must walk.

Burnham’s hedging emphasizes the political sensitivity surrounding Brexit in constituencies like Makerfield, where the Leave vote remains considerable. Should he obtain both the Labour candidature and take the seat, he would be positioned to initiate a challenge to the leadership against Sir Keir Starmer. However, his meticulously balanced remarks demonstrate the conflict between acknowledging Brexit’s financial impact and respecting the democratic mandate expressed in the 2016 referendum—a tension that will probably shape Labour’s leadership discussion.

Reform Party taps into pro-Brexit feeling

Reform UK has identified Makerfield as fertile ground for mobilising Leave voters frustrated with Labour’s ambiguous positioning on Brexit policy. The party has pointed out that 65 per cent of the constituency supported Brexit in the 2016 referendum, a significant lead that points to significant reservoir of support for candidates ready to defend the Leave decision. By contrast, Labour’s failure to firmly advocate for Brexit or articulate a coherent plan for the post-Brexit landscape leaves an opening for populist challengers to capitalise on.

The appearance of Brexit as a campaign issue in Makerfield reflects broader strategic calculations by Reform UK to establish itself as the genuine representative of Leave voters. As Labour party candidates discuss the party’s long-term ties with Europe, Reform UK’s readiness to defend Brexit defence provides a stark alternative narrative. This dynamic may complicate Labour’s efforts to retain the seat whilst at the same time handling party divisions over the party’s future European policy.

Burnham handles the European Union issue with caution

Andy Burnham’s reply to questions about EU rejoin exposes the precarious situation confronting Labour’s prospective leadership candidates. The Greater Manchester mayor, who is campaigning to become Labour’s candidate in the Makerfield by-election scheduled for 18 June, acknowledged that “in the long-term there is a case for that” when questioned about rejoining the European Union. Yet he quickly tempered this by noting he is “not advocating that in this by-election”, reflecting the party’s broader hesitance to commit openly to a pro-EU position that might estrange Leave-supporting constituencies.

Burnham’s carefully calibrated approach reflects his past remarks made publicly respecting the 2016 referendum outcome, maintaining that any step toward EU rejoin would necessitate a fresh democratic mandate secured through a general election. This careful approach allows him to demonstrate receptiveness to greater EU integration amongst left-leaning party members whilst simultaneously putting at ease Leave voters in traditional party strongholds. The balancing act underscores the political challenge Labour must navigate as it grapples with its post-Brexit direction and future direction under new leadership.

• Burnham recognises sustained rationale for EU rejoin but avoids active promotion
• Any EU rejoin would necessitate fresh electoral mandate from the British electorate
• Strategic positioning aims to satisfy both progressive and pro-Leave Labour voters

Conservative and opposition parties capitalise on the opportunity

The Conservative Party has moved quickly to exploit Streeting’s Brexit comments, with Party Chairman Kevin Hollinrake condemning Labour’s eagerness to revisit the EU question as a damaging distraction. Hollinrake argued that whilst Labour senior figures discuss European policy, the government continues unable to concentrate on the pressing concerns of British households and enterprises, particularly the rising cost of living and economic stability. This riposte demonstrates the Tories’ broader strategy of depicting Labour as obsessed with reversing Brexit rather than addressing immediate household concerns. The intervention underscores how deeply Brexit is entrenched in British political debate, able to rekindle partisan divisions at critical junctures.

Reform UK, in the meantime, has pinpointed Makerfield as fertile ground to advance its Brexit-supporting position and attract disaffected voters. The party has emphasised that 65 per cent of constituents supported Leave in the 2016 referendum, establishing itself as the authentic guardian of that mandate. By comparing its clear support of Brexit with Labour’s apparent lack of commitment and the Conservatives’ implementation challenges, Reform UK hopes to consolidate Leave voters under its banner. This three-way contest demonstrates how the question of Britain’s relationship with the EU continues to fracture traditional party loyalties and reshape electoral calculations across British politics.

What the resurgence means for Labour’s strategic path

The emergence of Brexit as a key focal point in Labour’s leadership race signals a significant reassessment within the party over its strategic approach and ideological stance. Streeting’s willingness to articulate what many in the party have privately thought—that EU departure was economically damaging—represents a challenge against the careful consensus Sir Keir Starmer has upheld since becoming leader. This fracture implies Labour’s future leader may come under pressure to take a clearer position on European engagement, potentially transforming the party’s attraction for Remain-supporting constituencies and younger people who regard Brexit as a defining policy failure.

However, the party faces a delicate balancing act. Labour’s long-established working-class strongholds, illustrated by constituencies like Makerfield where 65 per cent backed Leave, stay deeply doubtful of any call to reverse the plebiscite result. Candidates like Andy Burnham must navigate this tension with care, acknowledging long-term possibilities whilst preventing the alienation of Leave voters in crucial by-elections. The consequences of these conflicting leadership directions will likely determine whether Labour attempts to heal the Brexit divide or treats it as a enduring characteristic of British politics, with profound consequences for the party’s electoral prospects and governing agenda.
