The article text supplied for this piece does not actually contain any content about trade unions or single-sex spaces. Instead, the scraped text consists entirely of unrelated Daily Mail navigation links and headlines covering other stories (Prince Harry and Meghan Markle, celebrity news, and various unrelated crime and lifestyle items), with no paragraphs relating to the stated title.

As a result, I cannot produce an accurate summary of "Trade unions vow to fight against single-sex spaces" from the material provided, since none of the actual article body appears to have been captured. Please provide the correct article text or check the source link so I can summarise it properly.
