Widnes Vikings are top of Super League after thumping London 64-10.
Although the Broncos started in determined fashion, taking the lead with a Mason Caton Brown try after six minutes, it became one-way traffic thereafter.
For Vikings Kevin Brown was outstanding and grabbed a hat-trick, with Danny Tickle also catching the eye with a try and ten goals on debut.
Jack Owens started the ball rolling for Vikings, and he was followed over the whitewash in the first half by Tickle, Brown, 2, and Stefan Marsh to make it 30-6 at the break.
Paddy Flynn, who had an outstanding game, was rewarded with the first try of the second half as the Vikings ran riot.
Chris Dean forced his way over from close range and then Joe Mellor leapt to cross for another.
Brown brought up the 50 with his hat-trick, but Caton Brown was able to post a consolation for the visitors.
Vikings wrapped it up with Marsh and Dean grabbing their seconds of the afternoon.
The big win puts Widnes top - but they will not be getting carried away with the big tests to come.
their fans did allow themselves the chance of a cheeky jibe at neighbours Warrington, taunting Broncos with a rendition of 'Going down with the Wire!'
