And that seems like a good place to sign off for the day. Thanks for all your contributions today.

The race report is taking shape.

There will be live analysis of today's stage this evening on Facebook with OJ Borg, Rob Hayles and Simon Brotherton from around 18:30 BST, or check out the podcast a little later.

And I'll be back tomorrow morning from 11:00 BST for what I expect will be a sprint finish in Vittel.

Will Geraint Thomas remain in yellow? Will Mark Cavendish chalk up Tour stage win number 31?

Be sure to join me - and the five live team from 14:30 BST.

I've just seen pictures of Geraint Thomas picking up his yellow jersey. A bigger smile than yesterday.

That is a big stage ticked off for the Team Sky squad. It was a chaotic finish but it passed off without the incident and crashes that affected Sunday's stage.

Richie Porte said his attack wasn't premeditated "but the guys put me in a fantastic position"

However, he said he realised "about 500m out it was a bit far" and when he saw Peter Sagan move in front of him he had no chance of winning.

"It's a shame I didn't pull it off," he added.

Peter Sagan is laughing. "What is pressure? he says before thanking all his team-mates for "pulling all day on the front".

He added: "It was a really hard climb. After Richie Porte attacked I decided to go and I said to myself I was going too early. But I sprinted and my foot came out, another mistake, but I got my foot back in and I won. Matthews almost got me but I'm happy for the victory."

Geraint Thomas finished eighth, two seconds back, one place ahead of Chris Froome. Richie Porte, Nairo Quintana and Alberto Contador also finished two seconds adrift so there is no change in the time differences for the general classification contenders.

"Sagan is a freak," says Small Man Peaky on twitter at #bbccycling.

It's hard to disagree. To unclip in full sprinting mode and then have the ability to get back in and stay upright and sprint to victory. Sensational.

An eighth stage win for the Slovakian.

Chris Froome moves up to second place overall. He must have finished on the same time as Geraint Thomas because he is 12 seconds back.

A British one-two at the Tour after three stages. I'll settle for that.

I'll get a full run down of the results shortly, but suffice to say Geraint Thomas will start stage four in the yellow jersey as race leader. It also looks like Chris Froome appeared from nowhere to make sure he lost no time on his rivals.

A bit tough to see in the closing stages with riders falling back in the final 100m and others coming through.

That was incredible, such a hard hard finish and so difficult to call.

A nonchalant wave of the hand by Sagan as he crosses the line - it was never in doubt Peter eh?

That was closer than I think Peter Sagan realised. He looked like he was going to win that with ease but his foot unclipped from his pedal with about 200m to go.

The world champion clipped back in and still had the power to take it. Michael Matthews was catching with every revolution but needed another 10m.

Oh, what a long-bursting finish that was!

Porte has a few bike lengths lead and is really opening up this race. Peter Sagan is still in the wheel riding like it's the first kilo of the race.

Geraint Thomas also looking good.

There are no Team Sky riders up in the first dozen. But BMC are still leading this out.

Here comes Sky up the right. Michal Kwiatkowski bringing Geraint Thomas up there. Alberto Contador is also prominent.

Richie Porte attacks!

A big left-hander in the middle of Longwy and the road suddenly kicks up.

Richie Porte is up alongside Greg Van Avarmaet as the riders hit the steepest section with 1.5km to go.

Dan Martin appears down the left. Peter Sagan and John Degenkolb are also up there.

We are into the final 3km and most of it is uphill. It's a sharp kick up to the line after ascending Côte des Religieuses.

The climb is officially 1.6km at 5.8% but there is an 11% section.

Three BMC Racing riders are still leading the way as the road snakes down into Longwy.

The peloton is stretched to breaking point.
