Harriet Millar-Mills has a pick and go and her team-mates try to force her over.

France keep her on her feet though and we go back for an England scrum.

This is better. Amber Reed's cross-field kick to the corner is tasty and it bounces awkwardly for French wing Julie Billes, who has to stick it out.

England this time keep hold of the line-out but France repel them again - although at the cost of  scrum.

England are bouncing their way into the French defence with regularity but it's like a woodpecker having a nibble at Big Ben at the moment. They're getting nowhere.

I feel like we've entered a time loop. The line-out finds French hands, again.

Ceri Large's boot has its sighter calibrated as she puts a penalty to the corner.

But the line-out is messy and France can clear.

England charge back into French territory and it's another penalty, which Large once again puts to touch.

Brutal and punishing probing from England as they make yards with the maul and then Sarah Hunter and Harriet Millar-Mills take it in turns to try an edge towards the line.

But France hold on and win a penalty three metres from danger.

A bit of ball in hand for England from an attacking line-out, but just as they get the ball moving Katie Mason knocks on.

England need a breather here. They just kick into French territory and the hosts bring it back with ball in hand.

Once again England clear their lines and stick it out just short of their own 22.

Fortunately the throw from Gaelle Mignot is not straight and it's an England scrum.

Shank o'clock.

Camile Cabalou gets it all wrong - bit of nerves perhaps in front of this feisty crowd.

Amber Reed gives it a boot into France territory but the hosts come piling back up the field.

Number eight Safi N'Diaye is carrying beautifully and then Rocky Clark fails to roll away so France will have a crack at the posts.

The catch-and-drive from France on England's 22 disintegrates quickly but they recycle and go through the phases until they mis-handle in the tackle.

England scrum, so it's the first time they get their hands on the ball.

France think they are away here down the left but the referee is blowing manically for an England knock-on and the hosts kick to the corner.

Here we go. This is for all the marbles.

England are still doing some warm-ups... now they have to switch sides... and Camile Imart of France gets us under way.

Whatever the men can do, the women can do, well, first.

At least, they hope to.

One day before England's men look to wrap up a Six Nations Grand Slam in Paris, their female counterparts can do just that in western France tonight and beat the fellas to the punch.

Unlike tomorrow's France v England encounter, though, this is a title decider.

If England win, they will have blown away everyone in front of them and secured a 14th crown and 13th Grand Slam.

If France win, they claim the title on points difference. It could not be better poised...
