Leeds’ torrid start to the season worsened as London Broncos stunned the Rhinos with two late tries to register an 18-16 win.
Tries from Richie Myler, Trent Merrin and Luke Briscoe had seen Dave Furner’s side overturn an 8-0 half-time deficit. But late tries from Matty Fozard and Will Lovell secured the Broncos a third victory in the opening seven games of their Super League return.
The pre-season favourites for relegation, the Broncos are now four points clear of the bottom three with victories over the last two Super League champions under their belt.
A Kieran Dixon penalty goal and Jay Pitts try had established an 8-0 lead before Leeds hit back.
But two tries in the last six minutes consigned Leeds to a sixth defeat in seven games.
