Tom Sykes sealed his second win of the UK round of the World Superbikes at Donington Park to close the gap on leader Jonathan Rea to 56 points.
Sykes had won Saturday's first race and made it two from two after heading home Kawasaki team-mate Rea by just over two seconds in race two on Sunday.
Current world champion Rea, third on Saturday, pushed Sykes all the way but could not force a passing move.
Northern Ireland's Rea leads Sykes by 56 points in the 2016 title standings.
Ducati rider Chaz Davies from Wales made it a British clean sweep of the race two podium, but he drops to third in the overall championship points table.
Fourth went to the Ioda Racing Aprilia of Lorenzo Savadori from Leon Camier on the MV Augusta and Honda's Nicky Hayden.
Davide Giugliano, who was second in race one, finished seventh on the Aruba.it Racing Ducati ahead of Honda rider Michael van der Mark.
