Righto, I think we're going to wrap this all up. Remember, it's Scotland v France in Edinburgh tomorrow, which kicks of at 15:00 GMT as in live on the BBC. A Scotland win would hand England the title, a French win would take it into the final weekend. Peace and love.

Billy Vunipola had more carries than anyone, with 18. That's five more than the next highest, Dan Biggar. Man of the match Maro Itoje made more tackles than any other Englishman, with 14, although Welshman Dan Lydiate made 16.
Given England's dominance in the first half, you might be surprised to learn that Wales finished with 55% of territory and 51% of possession. That tells you just how much England were creaking in the final 20 minutes.
The battle of the number eights was highlighted by some before kick-off as where the match would be won and lost.
Taulupe Faletau scored a try, but childhood friend Billy Vunipola led on most of the other stats.
Wales coach Warren Gatland told ITV: "I'm very disappointed with the first half. I said to them at half time that we needed some energy. I told the players they needed to come up with answers themselves. In the second half we got sime impetus and finished strongly and we wonder what could have been.
"It was unlike us in the first half. We looked tired and didn't look enthusiastic. But I'm proud the boys didn't give up and they kept their heads.
"England competed hard. We outscored them 3-1 in terms of tries but it was Farrell's kicks that were the difference. The best team won and I take my hat off to them."
Get it into the stands!
England - 18 points clear with seven minutes to go - boot the ball in touch to scrape home with only four points of that lead remaining.
Matthew Harris: Wales won the story. But England won the match. I know what I'd rather have if i could only have one.
Jonathan Collard: Superb from England. Totally bossed Wales except for one interception and the last 5 mins
England head coach Eddie Jones on ITV: "It was one game for 60 minutes and another for 20. Luckily we got enough points in the first 60. It was a funny game, it was all Wales in the last 20. We dropped off a bit at the end.
"We made a number of changes on purpose to test players and to test the strength of the team and maybe those changes didn't work. If you look at our first 60 minutes there was some fantastic rugby.
"Maro Itoje - he's a BMW now (Jones described him as an Astra before the game).
"The Grand Slam is a reality and we can't wait to get to Paris and to do the business. We need to prepare well and the Grand Slam is there for us to take. France will play with a lot of passion and a lot of pride – I think we're good enough to do the business."
Twickenham jaws on the floor.
Taulupe Faletau muscles over in the 76th minute, Rhys Priestland adds the extras and suddenly England, a man down with Dan Cole in the bin, are in a world of danger.
Wales flanker Dan Lydiate told ITV: "We didn't get out of the blocks in the first half, but all credit to England. It left us too much to do. I wish we'd had another 10 minutes.
"We didn't spark. Preparation went well during the week but it wasn't there. In the second half we got back into it but it was too little, too late.
"England came out firing but we've got to take a look at ourselves."
Hope for Wales!
George North races in as Wales slice England open from first-phase ball with seven minutes left to cut the deficit to 25-14.
England's man of the match Maro Itoje on ITV: "It was pretty tough, especially the last 20 minutes. Thank God we managed to see it through.
"We talked through the different scenarios in the week and luckily we had enough time to see it through.
"This was a slightly different team to the game against Wales at the World Cup and this team is setting our own standards and our own goals."
England full-back Mike Brown ran the ball back with interest all afternoon.
Ex-England man Will Greenwood reacts to the near-comeback from Wales:
Former dual code international on BBC Radio 5 live
"Maro Itoje was immense for England, a brilliant performance. England choked a bit towards the end and cramped up. It was a delight to see Wales play a different game and they showed what they're capable of. England deserved the win, they were the better side for 70 mins. I think they go to Paris a firm favourite and I can see them winning the Grand Slam. For Wales it’s a chance to shed Warren-ball against Italy next week."

"The closer the clock went to 80 the more pressure England would have been under. It’s a Grand Slam decider and it's massive. The two benches were going to be important and Wales had the better bench. Thankfully, the clock won for England."
England's last Grand Slam was as long ago as 2003, which is a remarkable stat for a country of its size and resources. On the evidence of the Six Nations so far, they should rumble France in Paris. Although it's not always that easy. As it is, it's the second time in three years that England have won the Triple Crown.
If France lose against Scotland tomorrow, which is a distinct possibility, it's England's title. If France win tomorrow, it's alive and heading into Le Crunch in Paris next Saturday. Who said the Six Nations was boring? Well, me actually, but it was a lot of fun today.
North once again down the left flank but Tuilagi tracks him and takes him down. England with the line-out and they manage to hang on to it. Care gets his hands on the ball, reels away and thumps the ball into the stands. Great game of rugby, the best of the championship so far by some distance.
Maro Itoje is named man of the match. Fine kick by Priestland, Wales in England territory again... Owens with the through to the back, it runs loose, Francis falls on it...
North again, flying down the left wing unopposed. Wales into England's 22 again... Faletau over! With Cole in the bin, England are on the ropes as the match reaches the championship rounds... Priestland, on for Biggar, lands the extras, that Triple Crown in danger of tipping from England's head...
North goes over in the left-hand corner. Great offload by Liam Williams, he feeds Jonathan Davies, who shovels it to North, who isn't going to miss from there. Great line by Williams, we could be in for a tasty last five minutes. Biggar kicks the extras.
An update from the Wales dressing room on captain Sam Warburton who was forced off after a collision earlier on:
Itoje is having a monumental game, this time he's all over Gareth Davies at the back of the scrum but gets pinged for not rolling away. Wales in the corner now, England give up another penalty, Dan Cole is sent to the bin for collapsing, might as well head to the changing room and start filling the bath.
The TMO is having a look at some potential foul play, looks like Tom Francis has a swipe at Cole's eyes. This could be a red card, big reaction from the Twickenham faithful...
Wales captain Sam Warburton was taken off on a stretcher after taking an accidental knee to the head from a team-mate, but gave a thumbs up to the crowd as he was wheeled away.
Christopher Worrall: Surely this is the best England performance since beating New Zealand in 2012?
Matthew Mansfield: Itoje is having an absolute stormer today

"I find it staggering that Wales go the same way every time - straight into the tackle. The defence just read it and pick the runners up. It's so easy to defend."
2003 World Cup winner on BBC Radio 5 live
"What a difference Owen Farrell makes for England. If you can guarantee 14, 15, 16 points a game you are so pivotal in these games."
Farrell with a good tackle on Charteris, Kruis gets over the ball and it's another chance for Farrell off the tee. Through it goes, I think we can safely say that England have just donned the Triple Crown.
England penalty, it's Tuilagi with his first carry and Luke Charteris has bent his finger attempting to get to grips with his armoured body. That was almost bent at a right-angle, nasty stuff, although I'm sure they'll just pop it back in. More importantly, that burst from Tuilagi led to a penalty, which Farrell converted.
Chief sports writer at Twickenham
"England losing control, losing their patterns. So on comes Tuilagi - Ford off, Farrell to 10, storm-hatches battened down..."
Harem-scarem stuff, which finishes with Cuthbert being dragged into touch. And here is the return of Manu Tuilagi, Ford off, Farrelll to 10. The Leicester man hasn't played for England since the summer of 2014.
George McAllister: England need to up their game. In danger of throwing away their current lead.
Jonny Duchezeau: The Welsh were right, Ford is the weak link.
Fly-half Dan Biggar has been taking responsibility as Wales begin to open up and chase the game.

"Manu Tuilagi is warming up and hitting a couple of bags. The guy who is holding them does not look too keen to be honest."
England scored the first try of the game, through winger Anthony Watson - click play to watch it below.
A much more even contest in the second half, as exemplified by this scrum, which goes nowhere. They go again and this time Vunipola attempts to dribble it up the pitch from number eight, it all goes a bit awry, but England win the penalty. Ford clears his lines...
