Burnham says Labour could promise EU membership referendum

Andy Burnham has said Labour's next general election manifesto could promise an in-out referendum on EU membership.

The prime minister spoke ahead of a UK-EU summit in Brussels on Friday 20 November, where he wants closer ties with the EU. Downing Street said early wins are possible on youth mobility, food and drink, and energy. Mr Burnham has also said he would press for a deal to improve trade ties with the EU at next month's summit, Reuters reported.

Mr Burnham has said Brexit has done more harm than good. He used the same words at the Labour Party conference, Reuters reported. He has said the present settlement is not good enough for Britain.

The broader context here is Labour's existing red lines. At the last general election the party promised to stay out of the customs union, the single market and freedom of movement, according to the BBC. The customs union sets shared import taxes, the single market allows free movement of goods, services, capital and people, and freedom of movement is the right to live and work across borders. The question at Westminster is how a future referendum pledge fits with those promises, and what exact question would be put.

The summit strategy

Mr Burnham wants step-by-step deals in three areas: youth mobility, food and drink, and energy. No 10 said those deals can be ready before or at Brussels.

The history is well known in Whitehall. The Conservative Party's 2015 manifesto promised a straight in-out referendum by the end of 2017. The vote was held on Thursday, 23 June 2016. The UK left the European Union at 23:00 on Friday, 31 January 2020.

Mr Burnham gave a speech at the UN General Assembly on 22 September 2026, GOV.UK records. His recent comments on Europe followed that speech and party conference season.

Kemi Badenoch is the leader of the Conservative Party.

The BBC's political editor Chris Mason said that, for the first time since the UK left the EU, the UK has a prime minister who will "unflinchingly" debate Brexit. The BBC published an analysis titled "Why the Prime Minister wants to talk about Brexit again".

Looking at Westminster, the Opposition will be central to how any referendum plan is tested in Parliament and in a campaign.

The Russia claim

Mr Burnham told The Rest Is Politics podcast that on arriving in Downing Street he had asked if there was Russian interference in the Brexit referendum.

He has since gone further. Mr Burnham said Russia interfered in the 2016 Brexit vote, Reuters reported on 11 October. He warned voters in France and Germany about Moscow-backed efforts, the same report said.

The immediate questions here are about procedure and diplomacy. What briefing did he receive, from whom, and will any assessment be published or placed in the House library. The warning was aimed at voters in two allied states.

The broader context here is that prime ministers have largely avoided Brexit since departure. Successive governments treated the settlement as closed. Mr Burnham is reopening trade and cooperation talks without, for now, dropping the last manifesto.

Looking at what this means for the next phase, three tests stand out. First, negotiation. Brussels will want to know if youth mobility, food and drink, and energy are stand-alone fixes or the start of wider change. Second, politics at home. A possible pledge will encourage Labour MPs and members who favour rejoining, and opponents who will call it a breach of the last mandate. Third, process. Any in-out vote would need legislation, testing of the question by the Electoral Commission, designation of campaigns, and agreement on franchise. None of that is quick.

In my view, the summit matters more than the manifesto hint in the short term. A referendum promise signals direction. Deals in November would change rules for exporters, producers and young people sooner. Lobby watchers will read the communique line by line, especially on agri-food and energy, before judging the longer constitutional question. Mr Burnham appears to think openness about harm is less risky than silence about the status quo. Whether that holds through Brussels, Parliament and a campaign where Ms Badenoch's party will defend the 2016 result will shape Britain's next European argument.
