Hello, I'm Materialscientist. I noticed that you added or changed content in an article, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 01:02, 19 December 2023 (UTC)
Please do not add or change content, as you did at Tony Blair, without citing a reliable source. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. Thank you. Tim O'Doherty (talk) 21:24, 17 January 2024 (UTC)
