Round-up: New home, same result for wasteful Broncos A change of scene could not bring a change of fortune for the struggling London Broncos. Playing across the city at Leyton Orient's Brisbane Road while the Stoop is undergoing pitch repairs, the Broncos led 16-0 before collapsing to lose 29-22 to Bradford. The bulk of the damage was done by the Bulls' centre Michael Platt, who crossed for four tries, two on either side of half-time. London had led through tries from Michael Robertson, Matt Cook and a first for the club from the teenage centre Michael Channing. However, once Karl Pryce brought Bradford back into the game, the Broncos played into their hands with a series of what their coach, Rob Powell, called "simple errors." A former London player, Luke Gale, rubbed salt in the wounds with a late penalty and drop-goal that effectively clinched the match. Wigan ended the weekend on top of the Super League table, thanks to their 36-22 victory over Hull KR on Friday and Huddersfield's defeat at the Catalan Dragons. The Warriors will be without Pat Richards for the next 12 weeks following knee surgery, but he was hardly missed against Rovers. His replacement, Anthony Gelling, scored two tries and the stand-in kicker, Josh Charnley, five goals to go with his hat-trick of touchdowns. The lead changed hands six times in Perpignan, before Thomas Bosc's drop-goal and Vincent Duport's late try gave the Catalans a 27-20 win to keep them in touch with the leaders. Hull had a spectacular 34-20 win over Leeds, sealed by Tom Briscoe's spectacular long-range second try. St Helens were other convincing winners, overpowering Wakefield 38-12, with Chris Flannery contributing a hat-trick of tries.
