Team Sky's Elia Vivani was victorious on stage two of the 2017 Tour of Britain to move into the overall lead, as Edvald Boasson Hagen was relegated after winning the sprint finish in Blyth.
Boasson Hagen (Team Dimension Data), beaten in a photo finish on day one, crossed the line in Blyth first on Monday but was relegated for irregular sprinting.
Viviani had gestured to the Norwegian after crossing the line in second, feeling he had been impeded and - over 40 minutes after the stage finished - it was confirmed the Italian had won and taken the green jersey.
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 kilometres route and held off the challenge of Viviani and Dylan Groenewegen (LottoNL-Jumbo).
But Viviani and Groenewegen both immediately appeared to complain that Boasson Hagen deviated from his line.
Boasson Hagen told Dimension Data's website: "I know that I closed in Viviani but it wasn't on purpose. I was just sprinting for the line with my head down and when I looked up I was too close on the left side with Viviani on my inside.
"It's really a pity after all the hard work the guys did today. However, we will keep fighting and try to go for it again tomorrow."
