If France beat Wales in Cardiff next Saturday they will win the Six Nations title, unless Ireland beat England by at least 30 points at Twickenham. In that instance, Ireland would claim their first championship since 1985.
If France lose, Ireland would just need to beat England, while England could also still win the title if they were to beat Ireland by at least 40 points.
Scotland would need a 60-point plus win in Italy, while Wales will finish last if they lose and Italy beat Scotland.
