What makes the British?

An article in the July issue of Oxford Today magazine "What makes the British?" has just come to my attention. It's a popular account of the results of the Peoples of the British Isles project.
Based on a massive effort to collect blood samples, from 4,500 people from established rural populations throughout the Britain, the article describes at somewhat greater length than previously the DNA results, much as presented a year earlier at the Royal Society Summer Conference, and mention in a post here.
Although one science article has been produced it does not cover these results. Many people are waiting to see a peer reviewed publication describing the findings and methodology in more detail.
