Ireland v Italy (Kick-off 2.30pm) and England v Wales (Kick-off 5.00pm). The opening fixtures of the championship come from Croke Park and Twickenham respectively. The 2009 Grand Slam winners begin their title defence against the Azzurri, safe in the knowledge that they have never lost to them in this competition. Martin Johnson's tenure as England manager is likely to be defined by his team's achievements over the next six weeks, so getting under way in victorious fashion is considered as imperative today. Presented by Tom McGurk, with guests George Hook, Brent Pope and Conor O'Shea. Commentary by Ryle Nugent, Tony Ward, George Hamilton and Ralph Keyes.
