Guest: Dame Emily Thornberry, Labour MP and Chair of the Foreign Affairs Select Committee
Host: Nick Robinson, BBC Radio 4

Overview

In this episode, Nick Robinson sits down with Dame Emily Thornberry for a deeply candid conversation about the principles shaping Labour’s foreign policy, the constraints of international law, Labour’s internal struggles, and her own formative influences. Thornberry offers unusually frank insights about the challenges of aligning legal, moral, and political demands in a rapidly-changing world — especially with figures like Donald Trump and challenges like Iran. The episode is notable for its explanations of international law, self-reflection on Labour’s voice, and Thornberry’s personal journey from modest beginnings to political leadership.

Key Themes & Discussion Points

1. The Law of War, International Order & Responses to Iran

• International Law vs. Realpolitik
  • Thornberry is adamant that "You can't just say, I don't like you as a country. I'm going to bomb you. You can't do that. It's not the way it is. That's the law of the jungle. We cannot have chaos. The weak are the ones who suffer the most when there's chaos." (Emily Thornberry, 01:05)
• Britain’s Policy and American Pressure
  • Thornberry explains the careful legal, strategic, and diplomatic calculations behind Britain’s approach to US requests about military bases and Iran, highlighting the need for legality, plans, and national interest (04:42–05:57).
  • She argues the UK has a duty to be moral and uphold international law — “I think it is in Britain’s interest to be moral and to abide by international law. I'm sorry, I know now I sound like a lawyer, but… the reason why international law is the way that it is, it was largely written by British lawyers and it is in our interest for countries to abide by it. And we can't expect other countries to abide by it if we don't abide by it ourselves.” (Emily Thornberry, 10:23)

2. The Trump Factor & Labour’s Approach

• On Trump’s Rhetoric and UK-US Relations
  • Thornberry, reflecting on her famous description of Trump (“asteroid of awfulness”), now says, “I was completely wrong to call him an asteroid of awfulness. Because asteroids only hit the world once.” (Emily Thornberry, 01:46)
  • She unpacks the logic of engaging with Trump for Britain’s own interests post-Brexit and in supporting Ukraine, while insisting there's a line to be drawn: "When he gets like that, you have to stand up to him. I mean, you just can't. You can't be treated like that." (03:21)
• Clarity in Leadership
  • Robinson observes, and Thornberry concedes, that the official line can be murky: “Emily Thornberry has been clearer in the last three minutes than the Prime Minister has been all week.” (06:21)

3. Iran, International Agreements & Morality

• Failures of Multilateralism
  • Thornberry argues Trump’s rejection of the JCPOA (nuclear deal) was the turning point: “Well, why didn’t it work? Because Donald Trump got elected and didn’t like a deal that Obama had signed.” (11:53)
  • She pushes back on cynicism about international law, insisting, “Tell me something better. Tell me something better.” (11:28)

4. Personal Background & Political Values

• Upbringing and Legal/Ethical Foundation
  • Thornberry discusses her father’s internationalist legacy as a UN peacekeeper and her stepmother’s UN work. Despite being “a terrible father” who left her twice (13:01–13:32), she absorbed ideals about law, fairness, and global cooperation.
• Value of International Institutions
  • “The world… it's a fragile place and the only way we're going to make progress is by doing it together.” (16:03)
• Being Written Off & Class Background
  • Thornberry shares the formative memory of being told by her school careers teacher she would only be “visiting people in prison” — then turning that into a career as a barrister (16:42–17:02).
  • She notes the misconceptions about her own and Starmer’s backgrounds, pushing back against stereotypes of Labour being "North London liberal elite" (17:58).

5. Labour’s Identity & Electoral Struggles

• Challenges of Style and Substance
  • Reactions to newly elected Green MP Hannah Spencer's “authentic”, working-class voice spark a discussion on Labour’s perceived detachment and the need for “mean what we say and say what we mean and be confident in ourselves and not be self-conscious.” (20:16)
• Trans Rights and Social Conservatism
  • Thornberry candidly admits Labour has been "in the wrong place on trans" due to caution and self-consciousness, stressing, “trans people are on the margins, they are vulnerable. If the Labour Party doesn't look after trans people, what are we about?” (21:16–22:06)
• Immigration and Fairness
  • On immigration policy: “I think we need to…keep our feet on the ground.” She critiques the fairness of new policies, especially for individuals already living in Britain (25:46–26:53).

6. Reflections on Labour's Coalition and Inner Turmoil

• Learning From Past Coalitions
  • “We are the coalition on the left... Treat people with a bit of respect and understanding, appreciate there’ll be differences of view because you’re the coalition on the left.” (28:46)
• Green Party’s Rise
  • Labour’s challenge is to “say, 'look at all the things we're doing. We are leading ... on environmental policies. You should be with us.'” (29:32)

7. Personal Political Trajectory

• Thornberry’s Ups and Downs
  • Reflects honestly on her repeated 'kicking' by the Labour Party — not getting ministerial appointment, but relishing the role as Foreign Affairs Select Committee chair: “But I have been in politics for 21 years and I would love to have the opportunity to actually do something. ... I haven’t ever had the opportunity of being a minister, which is a shame.” (30:17–31:49)

8. Europe, Ambition, and National Strategy

• Relations with Europe and the US
  • Thornberry calls for “more clarity, more vision, more ambition” in re-setting relationships with Europe post-Brexit, warning Britain must negotiate actively and not be “low-key” or reactive (32:14–35:01).
  • “We need to be clearer, more ambitious, go faster with Europe, because I think this is an opportunity for us to reset and it's important for our economy.” (35:47)

9. Politics, Sexism, and Representation

• Gender and Leadership
  • Thornberry points to a regression in the gender balance of UK diplomacy and suggests Labour will eventually have a woman leader, citing the “groundswell” of female talent (40:47).

10. Political Language and the Public

• On Communication
  • Admits Labour sometimes feels awkward about being itself: “It's important that we say what we mean and mean what we say. ... People want their politicians to be human, but they also want us to be perfect.” (42:13)

Conclusion

This episode draws a vivid portrait of Emily Thornberry as both a product and a critic of her party and her country’s tradition, revealing the difficulties at the heart of British politics today. She champions legal principle, internationalism, and moral clarity — often more so, as Robinson notes, than the Prime Minister himself. At the same time, she is frank about her disappointments, Labour’s unease with its voice, and the challenge of keeping “the coalition on the left.” The conversation is rich, introspective, and timely, making it essential listening for anyone following Labour politics or Britain’s role in a turbulent world.
