The provided article text does not contain the actual story content — only the Daily Mail website's navigation menu and a list of unrelated headlines from other articles on the site. No substantive information about the Cambridge plagiarism row professor, the universities disputing their claimed academic positions, or the charity's concerns about their volunteering record was included in the text supplied.

As a result, a factual summary cannot be produced from this material. To summarise the story accurately, the actual body text of the article — detailing which universities are involved, the specific claims being disputed, and the charity's statement — would need to be provided.
