LEFT-CENTER BIAS
These media sources have a slight to moderate liberal bias.

These sources are generally trustworthy for information but may require further investigation. See all Left-Center sources.
- Overall, we rate The Observer Left-Center biased based on its liberal editorial identity, socially progressive coverage, and public-interest journalism focus. We rate it High for factual reporting due to professional sourcing, clear bylines, transparent new ownership, editorial-independence safeguards, and a clean fact-check record under Tortoise Media ownership.

History
The Observer is a British newspaper first published in 1791 and widely described as the world’s oldest Sunday newspaper. It was previously owned by Guardian Media Group and operated as a sister paper to The Guardian. In April 2025, ownership transferred from Guardian News & Media Limited to Tortoise Media Limited, and The Observer launched its dedicated domain at observer.co.uk. The Guardian stated that the ownership transfer became effective on April 22, 2025, while Tortoise announced the launch of the first dedicated website for the title following completion of the acquisition.
According to The Observer’s About Us page, Tortoise plans to operate The Observer as a seven-day-a-week digital publication alongside its weekly Sunday print edition. Tortoise describes The Observer as a liberal news publication focused on investigative reporting, independent thinking, and public-interest journalism. Tortoise Media was founded in 2019 and is known for long-form investigations, podcasts, newsletters, and public-interest tools such as Westminster Accounts and Peer Review.

Funded by / Ownership
The Observer is owned by Tortoise Media, which acquired the paper from Guardian Media Group and The Scott Trust. Tortoise has stated that it will invest £25 million in The Observer and combine the title’s print and digital journalism with Tortoise’s digital newsroom, audio, newsletters, podcasts, video, and investigative work.
The Observer’s About page states that all Tortoise Media shareholders are listed on Companies House, that new investors include Standard Investments and This Day, Gary Lubner’s philanthropic foundation, and that no investor has a controlling stake. It also states that investors agree to editorial independence and that an editorial board chaired by Richard Lambert, former editor of the Financial Times, exists to protect journalistic freedom and editorial independence. Revenue is generated through subscriptions, print sales, digital subscriptions, memberships, and related media products.
Analysis / Bias
The Observer is Left-Center biased based on its liberal editorial identity, story selection, and coverage priorities. It frequently focuses on public services, social equality, LGBTQ+ rights, institutional accountability, media freedom, health policy, climate, and democratic governance. However, its reporting is generally professional, well-sourced, and presented in line with conventional newsroom standards rather than strongly partisan advocacy.
For example, Princess backs NHS facial expression training to spot babies in distress reports on NHS health visitor training to identify infant distress. The article cites the Royal Foundation Centre for Early Childhood, the Institute of Health Visiting, South Warwickshire University NHS Foundation Trust, Humber Teaching NHS Foundation Trust, Prof. Sam Wass, and Kindred Squared. The article is health- and policy-focused, with credible named sources and no significant partisan framing.
In Keir Starmer’s speech cried out for a couple of gags – or perhaps a scream into the void, comedian Frank Skinner offers a clearly opinionated and satirical take on Keir Starmer’s speech. The piece uses humor and commentary rather than straight reporting, but it is clearly presented as a column by a named contributor.
Similarly, The hidden history of Britain’s fight for queer rights is a culture and history feature on LGBTQ+ archives and books. The article reflects socially liberal framing and attention to historically marginalized communities, supporting a Left-Center bias rating, while remaining within evidence-based feature journalism.
Overall, The Observer retains a liberal editorial identity and Left-Center story selection, but its current standalone operation under Tortoise Media appears transparent and professional. Its reviewed content is well bylined, uses named sources, and separates commentary from straight news. With the move away from The Guardian domain and the absence of direct failed fact checks under the new ownership, a High factual rating is appropriate.
