Johnston In Quest For The Plate Mark Johnston's Golden Quest heads a high-class entry of 67 for the John Smith's Northumberland Plate, run on July 1 at Newcastle.Boasting a total prize fund of £200,000, the two-mile handicap is unsurprisingly one of the major features of the racing calendar, with this year's renewal promising to be as competitive as ever.A maximum field of 20 will go to post, with notable performers Ouninpohja, Unleash and Bulwark among those likely to attract support if making the starting line-up.Ouninpohja acquitted himself well when second in a Musselburgh Listed contest this month, while Unleash may bid to repeat his 2003 success in this event.Bulwark was a well-supported winner of a competitive Haydock handicap recently, where the two-mile trip proved right up his alley. Many of the bigger stables are well represented at this stage, with Middleham handler Johnston holding an especially strong hand of six possibles. ? PA Sport
