"However good Wales were in Rome, Ireland's performance has just topped it... over to England! What a day..."

"I am massively, massively disappointed by Scotland. I expected them to come out and put on a performance. But they have laid down and that is very sad to see."
Madigan misses that penalty but it's a record-equalling win for Ireland at Murrayfield and possibly Ireland's title - their points difference is 10 better than Wales and England now need to beat France by 26 points at Twickenham to steal the title from them.
As it stands, England would need to beat France by 26 points to win the title. As poor as France have been, that seems highly improbable. Madigan pins Scotland in their own 22, all the noise in Murrayfield is of an Irish persuasion. Ireland penalty, O'Connell points at the sticks, they're already slapping backs up in the Ireland box, although no smiles from head coach Schmidt just yet.
That really was a tremendous, committed cover tackle from Jamie Heaslip and the wry smile on Hogg's face when the try was disallowed revealed he knew he didn't ground it. O'Brien is man of the match, at least according to former Ireland flanker Phillip Matthews on the BBC.
Ireland hammer away again - can they further extend their advantage over Scotland - and therefore Wales and England?
As it stands, this is Ireland's biggest win at Murrayfield. Scotland have scored! Stuart Hogg! Well, that is interesting, although the officials are going to have a look at a replay... good job they did, Hogg has dropped the ruddy thing, great work by Heaslip in the tackle...

"Sean O'Brien is just such a bullock of a runner. He has such presence in the loose and has been dominant today."
Chris Paterson
Former Scotland international on BBC One
"How impressive has Sean O'Brien been? He's been scoring tries as well as winning turnover ball at contact."

Ireland assail the Scotland line again... Heaslip held up, O'Brien reaches over for his second try... Ireland's points difference is now 10 superior to Wales', and Scotland have been pretty awful in the second half. One step forward, two steps back for Scotland at the moment.
Jonty Rhodes: Hope France have got the 'no tackling in the second half' memo from Italy and Scotland.
Toby White: I dream of a day when you'll be forced to put in to a scrum straight - not straight to the second row's feet.
Oliver Bywater: 'O spoon of wooden'...
Hogg looking to attack from deep but he gets isolated, coughs up the ball and Sexton spots the space left by the Scotland full-back and Seymour is forced to cover and take the ball into touch. Bennett has taken a knock to the head, Visser replaces him, there'll be a bit of a reshuffle out back for Scotland.

"That knock-on from Dave Denton was symptomatic of Scotland's Six Nations - plenty off good things in the build-up but they have just failed to execute properly to convert that into points and results."
Matt O'Brien: It's fair to say that Scotland are rubbish. #ShowSomePride
Edmund Inkin: Egad Scotland, you are an utter shambles.
Tony Walton: Must admit if England don't win the Six Nations, I'd rather Ireland did than Wales. But then I'd rather Liechtenstein than Wales. Or Ghana.
Phillip Matthews
Former Ireland captain on BBC One
"Ireland are really going to play a territory game now.
"It's a long time to hold on, but they'll try to hold Scotland in their own half and try to pick them off from there."
Ireland scrum just inside Scotland's half, after some cute work by replacement scrum-half Hidalgo-Clyne - Spanish father, Scottish mother, in case you were wondering. Murray with a diagonal kick but Seymour has it covered. But keep pinning Scotland in their own half and Ireland have the title won. Tonks on for Scott in the Scotland midfield.
