It's sort of funny how knee-jerk "Wikipedia is not a reliable source" has become. It is among other things a user-editable encyclopedia. It's also the largest project of the Wikimedia foundation, an online-encyclopedia development initiative with a paid staff, and one of the highest-traffic websites in the world. As you say, it is a primary source here. The question isn't what's on the Daily Mail's anyone-can-edit Wikipedia page, it's what a closed group of encyclopedia overseers have decided constitutes an acceptable source. What's more, the closest competitor, Britannica, relies on finding expert contributors instead of listing specific reputable sources, so its editors wouldn't be nearly as relevant here!
