A Warning to Keir Starmer drawn from His Personal History: If You're Not Bold on Brexit and the EU, His Party Challengers Will Be.

Back in 2018, it took just a short phrase to ignite the party's annual gathering and to show the party was becoming disillusioned with Jeremy Corbyn. While not exactly soaring oratory, the phrase were greeted with wild cheering as most of the hall rose in spontaneous acclamation.

When the noise subsided, Keir Starmer, remained at the lectern, visibly startled. He was unaccustomed to his speeches having such an effect. All he had said was: "We are not excluding staying in the EU". But context is everything.

During that darkly divisive time in 2018, departing from his agreed text like this was always going to be seen as issuing a challenge to Jeremy Corbyn, who was trying to prioritise Brexit voters in working-class seats above the Europhile sentiments within Labour. In just one speech, this seemingly cautious shadow Brexit secretary was transformed – if only for a while – into a risk-taker who would stand up for most Labour MPs, members and voters against the leadership he later succeeded.

The Evolution of Stance & Settled Debates

In the years since, the landscape has shifted, especially for Starmer himself. An early move after taking over from Corbyn in 2020 was to declare the Brexit issue had been settled by the previous year’s national vote. During the most recent campaign, he repeatedly emphasised manifesto “red line” promises that ruled out rejoining the EU, the single market or a customs union.

Similar to Corbyn, his strategy has been to pursue pro-Leave voters in target constituencies, despite polling evidence indicates a significant number have passed away or shifted opinion.

Pressure Building on Europe

Yet, it’s now Starmer is now to be an embattled Labour leader. And, if Europe may not be the central crisis in UK politics, a lid which was tightly sealed since Brexit is beginning to rattle again.

Both Starmer and Rachel Reeves have ramped up the rhetoric about the devastation that leaving the EU has caused to Britain's economic standing. This serves as an effective tool with which to beat the Reform UK leader, who now rarely mentions his flagship policy was his primary goal and remains his sole political accomplishment.

Nevertheless, the extent of the economic harm, reportedly has left Britain with an economy that is significantly diminished than if it were still in the EU, dwarfs the minor adjustments so far offered by ministers. Starmer’s so-called re-set deal agreed with Brussels last summer offers economic benefits quantified in fractions of a percent.

Cabinet Divergence & Ambitious Proposals

Rachel Reeves is among those trying to overcome entrenched Home Office resistance to a broader scheme designed to boost growth program for young people allowing young people can travel between Britain and Europe to study or work.

The deputy prime minister muses openly about the clear advantages of being in an EU customs pact, while a dozen Labour MPs, including the chair of the powerful finance committee, last week supported a Liberal Democrat motion on customs union membership.

While Nick Thomas-Symonds, the minister in charge of EU policy, now present at all cabinet sessions, insists the red lines remain unchanged, there exist avenues to work around them. One idea would be to declaring the commencement of talks immediately on a much bolder deal, for inclusion in the next manifesto, to be enacted only after Labour won a fresh mandate.

Starmer's Fundamental Doubts

Yet, Starmer has most recently pouring cold water again by warning rejoining a European customs area could undermine the commercial agreements with the US, which he regards as key accomplishments of his government.

Reportedly that the PM’s scepticism run even deeper, stemming from several key concerns.

  1. First, he thinks any customs union agreement is now much harder because his ministers busily de-aligning from European rules across a range of policy areas, like environmental standards.
  2. Secondly, the exorbitant price set for the UK for entry into the EU’s new defence fund and the ensuing failure of negotiations has led British officials that former EU partners are less interested in offering favorable terms with Britain and are more focused on demonstrating that Brexit does not work.
  3. Lastly, the new US national security strategy, which has been welcomed by the Kremlin, is viewed by key advisors in Number 10 as grounds for the UK to maintain distance from Europe.

An Alarming Document & Geopolitical Calculations

This bizarre and terrifying American strategy paper asserts Europe is threatened by cultural extinction because of immigration. It includes only one reference to Britain, placed beside a proposal that Donald Trump’s administration may interfere in British politics to foster the rise of “patriotic” parties.

But, far from deciding that this renders America an undependable ally, ministers is worried that aligning closer with Europe could upset the global balance by endangering precarious American backing for Ukraine, Nato and much more besides.

Leadership Speculation & The Echo of 2018

This situation brings us back to the conference of 2018. The PM has consistently stated that address was not a pitch for the leadership but simply an attempt to keep open the “option” of remain in a future vote. Indeed, in those days, he still supported a tailored trade agreement similar to the one he currently seems to reject.

Observers within the Prime Minister's office have noticed that Wes Streeting, who just about everyone assumes would stand in any leadership election, is part of a clutch of cabinet ministers letting it be known they want to go further on Europe.

Staff for Angela Rayner, another likely contender in a future race to replace Starmer, insist she refuses to comment on her position regarding a customs pact because it would only “fuel unnecessary gossip”.

The Clear Risk & A Prudent Reminder

The risk is clear. If Starmer rules out significant moves towards a close relationship, he cedes ground to occupy the space where the overwhelming majority of Labour MPs, members and voters reside.

It would be wise for Starmer to remember the impact just a few words had on his career seven years ago. Potential pathways for a big offer on Europe which the PM should not “rule out”; he should prise them open personally, rather than letting rivals adopt them as their own.
