Sir Keir Starmer has been accused of a “complete betrayal of the British people” as he comes under fire from both pro and anti-EU factions for the way he has pursued his “reset” with the bloc. The cross-party Foreign Affairs committee calls today for future agreements with the EU to be put to a vote in Parliament. It also wants a dedicated committee set up to scrutinise the country’s dealings with the EU and is pushing for the Government to set out a “coherent vision” for Britain’s relationship with the union in a White Paper.

Brexiteers warn Sir Keir is putting “British sovereignty on a silver platter” with his support for closer alignment with the EU, less than a decade after the country voted to break away in the historic referendum. But now even Labour voices are giving a withering verdict on his handling of relations with Brussels.

Dame Emily Thornberry, the Labour MP who chairs the foreign affairs committee, said the Government “reset is languishing, suffering from a lack of direction, definition and drive”.

She added: “It feels as though we are on a journey with no clear destination. In many areas, the Government has failed to provide timelines, milestones, or priorities and it does not appear to have an ambitious, strategic vision for the UK’s new relationship with the EU.”

Dame Emily called on the Government to “end its secrecy over EU matters, and set out exactly what it plans to do in the next phase of negotiations”.

Reform UK’s Richard Tice MP responded, saying: “Sir Keir Starmer’s Brexit reset has lost support even within his own party. It is a complete betrayal of the British people, and it will drag us back under EU control through a new customs deal and an uncapped youth mobility scheme that weakens our borders. “Starmer is choosing to hand back our sovereignty.”

Shadow Foreign Secretary Dame Priti Patel also set out her concerns, saying: “Throughout this process Labour have been reactive, opaque, and unwilling to spell out the trade-offs. Keir Starmer does not have the backbone to stand up to the EU and is eager to put British sovereignty on a silver platter to distract from his perpetual domestic woes. At a time when Europe faces profound security threats and businesses need certainty, Keir Starmer is too consumed by scandal and internal unrest to deliver for the British people. “Labour are still fighting the referendum because they fundamentally cannot accept the democratic decision the British people made. The Conservative Party will fight any Brexit betrayal.”

Veteran Brexiteer John Longworth, chairman of the Independence Business Network, said: “It is comforting that even pro-EU MPs are expressing concern about Starmer’s reset giveaway, with no benefit to the UK… This government is a risk to national security.”

Fred de Fossard of the Prosperity Institute also sounded the alarm, saying: “The Government has pursued its reset with the EU in great secrecy.”

He claimed: “Throughout the EU reset, the Government has given the EU everything it wants to ensure Britain is an uncompetitive, captive market for EU goods and produce… The EU is a declining market, and Britain should not realign with it.”

A Government spokesperson said: “Our priorities are clear: working in the national interest to deliver a strategic shift in our relationship with the EU through improved diplomatic, economic, and security cooperation. This includes securing a landmark food and drink trade deal and the carbon linking agreement by the next UK-EU Summit that will add £9billion a year to the UK economy.

“We are stripping away the costly bureaucracy and red tape that acts as a drag on growth, backing British jobs and putting more money in people’s pockets across the country.”
