The Guardian has published corrections and clarifications for several articles from the past week, aiming to maintain journalistic integrity and accuracy.
Correction on London Air Quality Report
In an article published on April 28, 2026, titled "London Air Quality Improves but Still Below Standards," we incorrectly stated that nitrogen dioxide levels had dropped by 25% in the last year. The correct figure is a 15% reduction, as confirmed by the latest data from the Greater London Authority. The error arose from a misinterpretation of preliminary data. We apologize for any confusion caused.
Clarification on Political Column
A column on April 27, 2026, discussing the government's new housing policy referred to a "senior Conservative MP" as having expressed support for the policy. The MP in question has since clarified that they were not supporting the policy but rather commenting on its potential impact. We have updated the online version to reflect this clarification.
Other Corrections
- Sports Section: An article on April 29, 2026, about the London Marathon incorrectly listed the winner's time as 2 hours 3 minutes 45 seconds. The correct time is 2 hours 4 minutes 12 seconds.
- Business Section: A report on April 26, 2026, about TechCorp's earnings misstated the company's quarterly revenue as £2.5 billion. The actual revenue was £2.3 billion.
We regret these errors and have made the necessary amendments to our online archives. Readers are encouraged to report any inaccuracies to our corrections team.
