increasingly insistent rumours have instanced a wish
This "instanced" sounds to me, I don't know, somehow upper-class. Worse, I had to look it up in the dictionary. Is it just me, or would there be a more common-language variant? *Lunatic*, n. One whose delusions are out of fashion.
increasingly detailed news items have made evident a wish...
(Though "instanced" is not a good choice, I don't think there's an "upper-class/lower-class" issue here. The language of a petition should be as exact as possible, that's all. If you deliberately write it in tabloidese, the kind of people who sign petitions will take no notice of it - sorry if that sounds snobbish, but it's a fact).
