Welcome to live coverage of stage six of the Tour de France where severe crosswinds could be a factor as the peloton take on the exposed 176.5km from Aix-en-Provence to Montpellier.

Yes, it's confirmed that Impey is the first African rider to take the yellow jersey - Gerrans finished three seconds down at the finish after a split in the peloton.

News that Daryl Impey has taken the yellow jersey from his Orica-GreenEdge team-mate Simon Gerrans because of stage placings at the finish.

Result: 1. Greipel, 2. Sagan, 3. Kittel, 4. Cavendish, 5. Lobato.

Andre Greipel takes the win ahead of Peter Sagan! Mark Cavendish gave it a good go, but he had to ride wide and then sat up towards the finish.

Under the banner and it's still Lotto taking it up. Sagan is on Greipel's wheel...

Now Lotto Belisol power through for Andre Greipel, with Matt Goss on his wheel.

It's a game of chess at the moment, but Argos now have six men on the front, with OPQS riding in their wheels. Lotto are there - so the teams of the big sprinters are getting prepared. The yellow jersey of Simon Gerrans is well placed - he wants to hold onto the race lead.

GreenEdge are quite a bit back, but Argos have come forward now for their men Kittel and Degenkolb. Many teams are trying to play the waiting game.

Lotto Belisol are beginning to make their presence known, with Cannondale tucked in behind BMC. Lampre are busy too.

Sky are near the front too, looking after Froome. Boasson Hagen may fancy his chances tonight - although he'll have to do it by latching on to the sprinters' trains. BMC are near the front, with Evans right there. It's a case of the GC teams wishing to keep out of trouble.

Now OPQS take it up on the front. At the back, Brajkovic cuts a sorry figure with a gash on his chin, knee and elbows.

The peloton is really strung out - those near the back have no chance on getting back now. Saxo-Tinkoff are doing a safety-first job on the front.

Brajkovic is a bit dazed. He's cut on the elbow and his knee clearly hurts. But he eventually gets back on his bike... He'll lose a lot of time today.

CRASH: A handful of riders go down, including Janez Brajkovic of Astana. The Slovenian stays down and it looks like he won't get back on his bike. Some Cofidis riders were involved too, but they were back on their way fairly quickly.

The road is so wide that two trains have formed either side - one led by Saxo-Tinkoff and the other by OPQS.

Now Omega Pharma-Quick Step have come forward to control the pace. Luckily for the peloton, the road is very wide here and there are smooth sidings as well, which means there certainly is enough space for a peloton that is clearly pretty nervous.

Belkin are on the front. They don't have anyone for the sprint - this is merely an exercise of keeping their top GC man, Bauke Mollema, out of trouble.

The Saxo Bank team of Alberto Contador have taken control of the pace and front the peloton ahead of the Sky team of Contador's big rival, Chris Froome. Mark Cavendish is right up there after that earlier scare. Cannondale, BMC, GreenEdge and Belvin are all heavily present.

Cavendish is back with the pack after that fall and subsequent chase. He'll now have to try and conserve as much energy as possible before the finish in Montpellier today. If he wins, that will be quite an accomplishment. Saxo-Tinkoff are on the front of the peloton now.

Sylvain Chavanel and Michal Kwiatkowski have come to the front of the peloton to slow the pace, while Peter Velits has gone back to help his OPQS team-mate Cavendish back on into the main pack.
