Injured Wales and British and Irish Lions centre Jonathan Davies joins the BBC TV team for the 2020 Six Nations Championship.
England's former captain Dylan Hartley and ex-Australia coach Michael Cheika are also among the new names to join the BBC's line-up, which once again features Martin Johnson, Paul O'Connell, John Barclay, Brian Moore, Jeremy Guscott, Andy Nicol and Chris Paterson.
BBC One will show live coverage of eight matches from the men's competition on BBC TV, iPlayer, radio, online and mobile app.
The Women's Six Nations also returns with selected games available to watch on BBC iPlayer and BBC Sport's digital platforms. Viewers will also be able to watch the highlights every Sunday night on BBC Two and BBC iPlayer.
All live programmes are available via the BBC Sport website and app, while there will be in-play highlights of BBC games and match highlights of every match shortly after the final whistle.
BBC Radio 5 Live or 5 Live Sports Extra will broadcast every home nations' men's game. Live commentary of every England women's game will be broadcast on 5 Live Sports Extra or online, with highlights on the BBC Sport website.
You can also download the Rugby Union Weekly podcast from the BBC Sounds app as former England winger Ugo Monye and rugby correspondent Chris Jones debate the biggest talking points with special guests.
And this year there will also be a new Women's Six Nations podcast every Wednesday covering all the news and views from their tournament.
The BBC Sport website will also have live text commentaries of every men's match and selected matches from the women's competition in addition to reports, features and pundit columns.
