An Caution to Keir Starmer from His Personal History: If You're Not Bold on Brexit & Europe, His Party Challengers Shall Be.

Seven years ago, it took just eight words to ignite the party's annual gathering demonstrating the party was becoming disillusioned with its then leader. While not precisely stirring rhetoric, the words met with wild cheering as most of the hall rose in an impromptu ovation.

When the noise subsided, the then-Brexit spokesman, remained at the lectern, visibly startled. He wasn't really accustomed to his speeches having such an effect. His statement was simply: "Nobody is ruling out staying in the EU". Context, however, is key.

In that deeply polarized period in 2018, departing from his agreed text like this was always going to be seen as laying down the gauntlet to the party leader, who sought to prioritize Brexit voters in working-class seats above the Europhile sentiments within Labour. In just one speech, this grey-suited opposition Brexit spokesman underwent a transformation – if only for a while – into a political gambler who would stand up for the party's base against a leader he later succeeded.

The Shift in Position & Settled Issues

Since then, the landscape has shifted, not least to Starmer himself. An early move after taking over from Corbyn in 2020 was declaring the Brexit issue was resolved by the 2019 general election. During the most recent campaign, he consistently stressed manifesto “red line” commitments that forbade re-entry into the European Union or its core structures.

Like his predecessor, his strategy has focused on winning pro-Leave voters in key seats, even if survey data suggests a significant number have passed away or shifted opinion.

A Lid That Rattles on Europe

However, it’s now Starmer is now to face the pressures of being a Labour leader. While Europe is no longer the boiling pot of British politics, the cap which was firmly shut for five years is beginning to rattle once more.

The Prime Minister and Chancellor have intensified the rhetoric about the devastation caused by Brexit has inflicted on 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 is still his sole political accomplishment.

And yet, the extent of the economic harm, reportedly has resulted in an economy that is between 6% and 8% smaller than if it were still in the EU, dwarfs the micro-mitigation so far offered by ministers. The PM's much-touted re-set deal negotiated with the EU last summer provides gains quantified in low decimal points.

Internal Pressure & Ambitious Proposals

Rachel Reeves is one of those attempting to bypass entrenched interior ministry opposition to an expansive version designed to boost growth youth mobility scheme by which young people can travel between Britain and Europe for work or study.

The deputy prime minister has pondered publicly regarding the “self-evident” benefits of being in a customs union with the EU, while a dozen Labour MPs, including the chair of the Treasury select committee, last week supported a Liberal Democrat motion on customs union membership.

While Nick Thomas-Symonds, who oversees EU policy, who is now attending every cabinet meeting, insists the firm boundaries remain unchanged, there are ways to work around them. One idea would be to declaring the commencement of negotiations now for a more ambitious agreement, for inclusion in the following election platform, with implementation only if securing a fresh mandate.

The Prime Minister's Fundamental Doubts

However, Starmer has most recently damping it all down on the idea by warning rejoining a European customs area could undermine the trade pacts with America, which he views as key accomplishments of his government.

It is understood that Starmer's doubts go still deeper, and is rooted in several key concerns.

  1. Firstly, he thinks a customs pact has been made significantly more difficult as ministers are busily de-aligning from European rules across a range of sectors, including the environment.
  2. Secondly, the prohibitive cost set for the UK for entry into the EU’s new defence fund and the ensuing failure of negotiations has led British officials that European nations are less interested in cutting special deals with Britain and are more focused on demonstrating that Brexit does not work.
  3. Thirdly, the new US national security strategy, praised by Moscow, is seen by some influential figures in Downing Street as a reason for Britain to maintain distance from Europe.

A Bizarre Strategy & Geopolitical Calculations

This strange and concerning American strategy paper claims Europe is threatened by “civilizational erasure” because of Muslim migration. It contains only one reference to Britain, found on a suggestion that the US government will intervene in British politics to foster the rise of nationalist movements.

But, far from concluding that this makes the US an undependable ally, ministers is worried that deeper EU integration would destabilise geopolitics further by risking fragile US military support for Ukraine, Nato and much more besides.

Leadership Speculation and The Ghost from the Past

All of which returns us to 2018. The PM has consistently stated his speech was not a pitch for the leadership but simply an effort to preserve the possibility of staying in the EU in a future vote. Indeed, back then, Starmer still favoured a tailored trade agreement of the kind he currently seems to reject.

Observers within the Prime Minister's office note that Wes Streeting, who just about everyone assumes would be a candidate for the leadership, is part of a group of cabinet ministers letting it be known they want to go further regarding the EU.

Staff for the Deputy Prime Minister, another likely contender in a future race for the top job, insist she refuses to comment on her position regarding a customs pact because it would only “escalate unhelpful speculation”.

The Clear Danger and A Wise Reminder

The risk is clear. Should the PM reject more meaningful steps towards a close relationship, he allows rivals to claim the territory where most of Labour MPs, members and voters are to be found.

It would be prudent of him to recall the impact that a short phrase had for him seven years ago. There are options for a major proposal on EU relations that the prime minister should not “rule out”; he should explore them himself, rather than letting rivals adopt them as their own.
