Voy Por Ustedes, ridden by Robert Thornton, notched his second Cheltenham Festival success with victory in a dramatic Seasons Holidays Queen Mother Champion Chase on day two.

The 5-1 shot, trained by Alan King, was following up his battling victory in the Irish Independent Arkle Trophy 12 months ago.

Thornton, who hails from Stratton Audley, near Bicester, took up the running on Voy Por Ustedes at the last, and his mount galloped on strongly to beat Dempsey (20-1) by a length and a half, with River City (33-1) five lengths away in third.

But there was a shock as early as the second fence when Well Chief, the even-money favourite, fell.

Reigning champion Newmill finished fourth, while Ashley Brook fell at the last when looking set for third.

It was a second big-race success at this year's meeting for King and Thornton following their triumph with My Way De Solzen in the Arkle Trophy on Tuesday.

The jockey commented: "I can't believe it, it hasn't sunk in yet. We picked up going to two out and my lad kept digging right to the line.

"When we quickened after the third-last I could see from a mile out that he was going to get in short at the next and the main priority was to get over in one piece as it is a tricky fence.

"He did get in tight and landed in a heap, but he has gone away and winged the last.

"Like with My Way, Alan said not to panic and those words stuck in my mind.

"They often go off very quick and then settle into a rhythm, which is what they did."

King said: "He was a bit forgotten about after his run at Newbury, which didn't go quite according to plan, but we've been thrilled with his preparation and the ground came right for him.

"He's a much better horse when it dries up, so I was quite pleased when I walked the course and Choc' (Thornton) gave him a wonderful ride.

"He got in a bit tight at the second-last, but he stays very well.

"I was looking forward to today and it's great for the team."
