Dewsbury Rams slipped to a seventh straight in the Betfred Championship as they went down 64-6 away to London Broncos last Saturday.
The Rams had little answer to the full-time Broncos, who ran in 11 tries, 10 of which were converted by Jarrod Sammut.
The Rams only reply came from a 67th minute try by Danny Ansell, which James Glover converted on a disappointing afternoon at Ealing Trailfinders.
Dewsbury handed debuts to loan signings Cameron Scott and Lewis Heckford, with Ansell replacing injured captain Paul Sykes at stand off.
Both sides were guilty of handling errors in the opening stages but it was Dewsbury who had a chance to take a 14th minute lead but Glover was wide with a penalty attempt from in front of the posts.
London forced the Rams to drop out and broke the deadlock from the resulting set as Eddie Battye drove the Broncos forward before sending captain Jay Pitts racing over for a try which Sammut improved.
Daniel Harrison produced an excellent tackle to deny the Rams before London clicked into gear.
Rhys Williams broke through on the last tackle and kicked through for Sammut to pounce for his first try, which he converted.
Alex Walker was caught by a high tackle and from the penalty, Sammut fed Matt Davis who forced his way over, with Sammut again on target with the conversion.
Sammut kicked the ball forward before a loose pass hit the ground and he chased forward to regather and score next to the posts to give himself a simple conversion as the Broncos led 24-0 at half-time.
London extended their lead after 48 minutes when a penalty put them on attack and Ben Evans crashed over, with Sammut converting.
Will Lovell was introduced from the bench and extended the lead two minutes after coming on as he weaved through the defence and over for the try, which Sammut improved.
The Broncos ran away with the game in the final quarter as they added a further 28 points.
Rhys Williams scooped up a dropped pass from Rob Worrincy and powered his way to the line, with Sammut converting.
Williams added his second try five minutes later, but Sammut hit the post with his conversion attempt.
The suffering Rams fans finally had something to cheer when Ansell scooped up the ball after London knocked on and raced away to score, with Glover converting.
London regained their supremacy and ran in a further three converted tries in the final seven minutes.
Elliot Kear brought up the Broncos half century when he crossed after 73 minutes.
Matt Davis then grabbed his second before Sammut completed his hat-trick and he added all three goals to end with a personal tally of 32 points.
Defeat leaves the Rams eighth in the table, level on six points with Barrow and Sheffield and four ahead of Rochdale, who they meet on Sunday.
