Having survived his piece of work, the colt was cut to 14-1 (from 16-1) by William Hill. Salford City was ridden in his work by Johnny Murtagh and was accompanied by Massif Centrale (Dane O'Neill), who was among the Derby acceptors at the latest forfeit stage but is not a certain runner."It was most satisfactory," Elsworth said. "We have trained him since the Guineas so that we could run in Derby if we wanted to and it is looking increasingly likely that he will. He hasn't run since the Guineas and this outing can only have done him good. The owner [Michael Tabor] is quite keen to run and there is only one Derby."There was a Derby-confirming workout elsewhere, when Pukka completed his morning assignment at Newmarket. Luca Cumani's colt won a Newbury handicap on his return earlier this month to warrant a quote of 66-1 from William Hill to give the Newmarket trainer his third Derby, following wins with Kahyasi in 1988 and High-Rise 10 years later."He worked fine this morning and we are happy with him," Sara Cumani, the trainer's wife, said.

"He carries on towards the Derby providing he [Cumani] is happy with him after Saturday, when he'll have another spin."Pukka would have gone to Epsom had the strangles outbreak not occurred, but was nevertheless presented with a Derby-style bend. "We had no option but to make a decision early yesterday and we contacted all of the 250 guests we were expecting by the end of the afternoon," he said. "But, happy that every precaution had been taken to minimise any risk of the disease spreading, we were pleased that some trainers still wanted to come to Epsom to work their horses this morning."Another peril to the smooth running of this year's Derby could yet materialise if a ballot of stalls handlers produces a vote in favour of industrial action when the result is announced today. Wallis indicated that course officials would resort to a flip start if Epsom finds itself in the front line.The happiest of the visitors yesterday appeared to be Elsworth after the light movements of his Greenham Stakes winner, Salford City. Yet there were trainers who turned up with their Classic hopefuls, adding substance to the official belief that the outbreak would not affect the Blue Riband, due to be run a week on Saturday. Over 250 guests had to abandon plans to attend a pre-Derby "Breakfast with the Stars" at Epsom yesterday when two cases of the highly infectious disease strangles were confirmed at a nearby livery yard. The race went to Moore's father, Gary, who trained the winner Lightning Star, who was ridden by Tony McCoy.Moore will be banned on from 6 to 10 June inclusive, then 12, 13, 15, 16 and 20 June.

But the jockey also rode a treble, partnering Wayward Melody and Tioman to complete a treble for his father, and Shannon Water's for Pipe.The Horse Racing Channel announced it would start broadcasting on Saturday, 13 days before its rival At The Races. In the meantime, all we can do is continue to liaise with the vet who is looking after the situation."The gala breakfast was first organised and then cancelled on Tuesday by Epsom's managing director, Stephen Wallis. "But it has never been part of the routine of horses stabled there to come this way up the hill, or anywhere near the racecourse stables. "All the livery yards around here have shut up and everybody is taking things very seriously," he said. John Gosden's Percussionist visited the track for the gentle stroll of a reconnaissance mission.Andrew Cooper, the clerk of the course, remained confident that his Classic meeting was not under threat. Jamie Moore was handed a 10-day suspension for dropping his hands and losing third place on Just Midas in the Gerrard Wealth Management Selling Hurdle at Fontwell yesterday. Riding for Martin Pipe, the conditional jockey was caught close home and beaten three-quarters of a length by Grand Prompt after easing down prematurely in the 10-runner contest. The channel, under the new brand name of Racing UK, will cover races from Kempton, Doncaster, Musselburgh and Cartmel..
