The Russell Group is basically a group of "elite" research-intensive universities. I think it's grown by few universities over the last ten years or so.
As Germanshepherdsmun says, employers wanting a graduate for a graduate position do still tend to choose one from a Russell Group. I think I read that more than 60% of graduate-level jobs requiring a degree go to these students.
