LONDON: The left-wing British Green Party has said it wants to separate the Church of England from the state if it wins the next general election, which must be held before August 2029.

The Church of England has been the "established" church since the 16th-century Reformation, with the British monarch serving as its supreme governor. For traditionalists, this link is not merely ceremonial but is the foundational bedrock of British identity.

The Greens have come under fire for seeking to remove centuries of British history and tradition by separating the church from British politics, with critics characterizing it as the latest move against Christianity in the U.K.

GB News reported last month that the Green Party policy document stated: "No person shall hold office in the state, or be excluded from any such office, by virtue of their or their spouse's membership or non-membership of any religion or denomination of religion."

Michael McManus, the director of research at the Henry Jackson Society, a U.K. think tank, told Fox News Digital, "Britain is a tolerant society but with clear Christian origins and culture. Aiming to disestablish the Church of England could be seen as an attempt to reject that ethical foundation without being clear what would replace it instead."

High-profile figures have also weighed in on the debate, with actor and comedian John Cleese responding to a comment about the Greens' proposal by stating on X: "The UK has always been based at the deepest level on Christian values, regardless of dogma. Despite the many mistakes made by churches, for centuries British people have been influenced by Christ's teaching. If these values are replaced by Islamic ones, this will not be Britain anymore."

The Greens are a growing political force, placing second behind Reform UK in a recent YouGov poll. Another YouGov poll linked the Greens' rise in popularity with younger voters in the country, finding a majority of those between 18 and 24 supported them, while also doing well with women and other groups.

A spokesperson for the Green Party told Fox News Digital, "We will be setting out our detailed plans for government at the time of the next General Election just as we did at the last General Election. As always, our members will be shaping our priorities. These will again address the real and immediate needs of people and the planet, such as tackling the climate crisis, bringing down the cost of living and rebuilding our public services, including the NHS. Our focus is on the issues that impact ordinary people most."

Green Party leader Zack Polanski has defended a secular state. He has also drawn criticism for his support of legalizing drugs such as heroin and cocaine, his climate policies and anti-Israel positioning.

The timing of the Green Party's push is particularly sensitive as it comes on the heels of the House of Lords (Hereditary Peers) Act 2026, which passed last month, removing the last hereditary aristocrats from Parliament. With the hereditary principle gone, the presence of the "Lords Spiritual" has become the next logical target for constitutional reformers. There are currently 26 seats reserved for Church of England archbishops and bishops in the House of Lords.

As the U.K. heads toward a local 2026 election cycle, the "Church and State" debate looks set to become a wedge issue. For the Greens, it represents their commitment to a "diverse and inclusive" Britain. For their detractors, it is a dangerous move that risks "de-Christianizing" the country at a moment of profound social uncertainty.

Whether the proposal will mobilize a new "religious vote" or simply fade behind the urgency of other issues remains to be seen. What is clear, commentators say, is that the image of the established Church is increasingly being viewed through the lens of a much sharper and more polarized political fight.
