The Sunday Times has today published an advert in the Chicago Tribune. The ad is an open letter from David Walsh, Chief Sports Writer at The Sunday Times, to Oprah Winfrey ahead of her interview with Lance Armstrong on Thursday, January 17.

The advert was put together by The Sunday Times in-house editorial team and lists the 10 questions that David Walsh suggests Oprah asks Armstrong.

People will get another chance to read David's Sunday Times Magazine article and view the video of his Times+ live event from December. These will be hosted on a public page today - thesundaytimes.co.uk/lance.
