Britain Elects with did some polls after the Oprah's interview on the 9th March with 1056 adults. This was done between J.L.Partners and the Daily Mail. The survey has a series of questions with breakdowns based on age, gender and regions in which are found in the spreadsheet. Unfortunately, I cannot attached the spreadsheet to this post.

Britain Elects has also tweeted out the overall/generalised results. I have slightly changed the spacing and formatting to make it shorter.
