Tour of Britain: Mark Cavendish helps Fernando Gaviria to stage win
Mark Cavendish helped Etixx - Quick-Step team-mate Fernando Gaviria to victory on stage four of the Tour of Britain.
Cavendish guided the Colombian to a sprint finish at the end of the 217km route from Edinburgh to Blyth.
Gaviria held off German Andre Greipel to win in a time of five hours 13 minutes eight seconds with Norwegian Edvald Boasson Hagen in third place.
Movistar's Juan Lobato (Spain) finished 15th to retain the overall lead.
The race ends in London on Sunday.
Welshman Owain Doull - riding for Sir Bradley Wiggins' team - remains in contention, 14 seconds off the lead in sixth place.
Wiggins - using the Tour of Britain as preparations for his European Track Championships and Rio 2016 campaigns - is in 101st place overall, nearly three minutes down.
Analysis from BBC Sport's Matt Slater
"Mark Cavendish started this Tour of Britain by losing the first stage by about an inch and then launching into a defence of the sprinter's art.
"His main point was that the Vuelta, with its emphasis on gear-grinding gradients, has forgotten that sprinters are good riders too, and a bunch sprint can make for great TV.
"It has taken three days but Cavendish can now point to some compelling evidence, although his star witness is team-mate Fernando Gaviria, the winner of a thrilling fourth-stage sprint into Blyth.
"With Cavendish widely expected to be leaving Etixx - Quick-Step next season, this will no doubt prompt some to speak of a changing of the guard.
"But I am not ready to write off the Manxman just yet - he has made a nonsense of such predictions before - and it should be noted that it was Cavendish leading the celebrations even before Gaviria had crossed the line."
