BBC Sport is in Rome, London and Carfiff for live coverage of the conclusion to the 2009 Six Nations contest, which has lived up to pre-tournament expectations of an exciting and open competition. The Calcutta Cup is at stake at Twickenham, where England are hosting Scotland. The Scots have enjoyed some famous victories over their great rivals over the years, but have not won at the home of English rugby for 26 years. Match commentary comes from Andrew Cotter and Brian Moore, while Gabby Logan's studio guests include three former internationals who know just what this fixture means to both teams: Lawrence Dallaglio, Jeremy Guscott and Andy Nicol.
