Welcome to live coverage of stage 17 of the Giro d'Italia, an undulating 230km trek from Feltre to Tirano.

Diego Ulissi is declared the winner! Visconti has been relegated to third place by the race organisers. What drama! But surely the correct decision.

If Visconti was Mark Cavendish he would have already been disqualified for irregular and dangerous sprinting.

Provisionally the win has been given to Visconti, with Ulissi and Lastras taking second and third. But that is quite controversial: he really pushed his compatriot there and it could have been very dangerous.

The peloton comes home at 3:02. Result is still undecided...

That would be a big blow for Visconti because he was clearly the strongest sprinter, he just didn't have any space to play for and reacted badly.

Visconti was boxed in between Ulissi and the barriers in the approach and he pushed his rival away, gesticulated, and then rode on to the win. Ulissi was second, and Lastras third. But this one will be decided by the judges...

Visconti crosses the line in first, but there will be a stewards enquiry there surely!

The two Italians Ulissi and Visconti come to blows in the final straight!

Bakelants is on the front. Suitsou is leading the chase behing, but surely it's too late.

Ulissi leads out the sprint, before turning off the gas and tucking in at the back.

Now they're looking at each other as they pass the Flamme Rouge... Ulissi is on the front, followed by Visconti, Bakelants and then Lastras.

Lastras makes the first attack! And it's a big one... but Visconti checks his wheel, and the others follow.

One of these four will surely win it now. Although if they start playing games, they'll let the others back in it - they're just 5 seconds back.

The four have a little gap over the chasers as they cross the river and swing into Tirano.

Bakelants, Ulissi, Lastras and Visconti seem to be pulling out a little...

Lastras ups the pace and Visconti goes after him, forcing everyone to react. Taborre rides into a patch of gravel on the side of the road, but stays on his bike. That was close.

The leaders are down to the valley now. They have 3:09 so as stated before, one of them will be the winner tonight.

Nibali no longer on the front of the peloton: it's a RadioShack man followed by a Vacansoleil rider.

Taborre leads Lastras on the front.

Wow, these tight hairpin bends are vertiginous to say the least!
