Great Britain secured the top spot on the overall medals table after winning two golds on the final day of the Para-cycling Track World Championship, in Apeldoorn, The Netherlands.
Sophie Thornhill and pilot Helen Scott clinched the nation's first success of the day in the women's tandem sprint event, firstly overcoming Belgium's Greet Meskens and Anneleen Monsieur in the quarter-finals, before defeating Japan's Yurie Kanuma and Mai Tanaka in the semi-finals.
The duo then clinched gold by beating the Australian pairing of Brandie O'Connor and Breanna Hargrave in straight rides, with times their times of 13.619sec and 12.624sec, while Kanuma and Tanaka earned bronze for Japan after two victories over New Zealand's Emma Foy and Laura Fairweather.
In the equivalent men's event, there was also success for Britain as Neil Fachie and pilot Peter Mitchell combined to beat Spain's Jose Porto Lareo and Jose Villanueva Trinidad in both of the final rides, winning the first in 10.510 and before claiming the second in 10.591.
The Netherlands' Tristan Bangma and Teun Mulder took the bronze medal position.
However, there was a shock result in the women's C4-5 scratch race after Britain's Dame Sarah Storey missed out on winning her third gold of the World Championships after an incident with Mariela Analia Delgado, which saw the Argentine relegated.
The United States' Greta Neimanas took full advantage to complete the 40 laps in 13min 13.320sec to take gold, with Poland's Anna Harkowska and Britain's Crystal Lane one lap adrift in second and third.

Brazil's Soelito Gohr and fellow Australian Michael Gallagher edged into the silver and bronze medal positions in a sprint finish.
The hosts enjoyed their fourth gold medal of the World Championships thanks to Alyda Norbruis, who has proved to be one of the stars of the meet, as she secured her third rainbow jersey by winning the women's C2-3 10km scratch race in 16:15.676.
C3 500m time trial champion Jamie Whitmore of the US was again among the medallists, winning her second silver of the World Championships, while Germany's Denise Schindler added a bronze to her C3 individual pursuit gold.
