London - Sky's Elia Viviani was made the winner of stage two of the Tour of Britain on Monday after Edvald Boasson Hagen was relegated for irregular sprinting after crossing the finish line first.
Boasson Hagen was also edged out in a photo-finish in Sunday's opening stage and had already donned the leader's green jersey on the podium before the gut-wrenching decision was made.
Viviani gestured angrily to the Norwegian after crossing the line in second, feeling he had been impeded.
The Dimension Data rider had started his sprint down the middle but moved left, failing to leave Viviani space along the barriers.
Over 40 minutes after the stage finished - it was confirmed the Italian had won and also taken the green jersey because of the ten-second time bonus.
Boasson Hagen, a two-time Tour of Britain winner, had been released by lead-out man Mark Renshaw with just under 200 metres left of the 211-kilometre route and held off the challenge of Viviani and Dylan Groenewegen.
Groenewegen moved up to second after Boasson Hagen's misery and Fernando Gaviria was third.
Several riders attacked, including a late effort from Belgian puncher Philippe Gilbert, who was reeled in with 5km to go.
