Dina Asher-Smith will compete in both the women's 100 metres and 200m at the World Championships in Doha later this month, it has been confirmed.
Triple European champion Asher-Smith has been named in a 72-strong team announced by British Athletics for the IAAF's showpiece event, which starts on September 27 until October 6.
Adam Gemili and Zharnel Hughes will also double up in the men's sprint events and European champion Matthew Hudson-Smith will take on the world's best in the 400m.
Laura Muir, who also won European gold last summer, will be focusing on the women's 1,500m and Katarina Johnson-Thompson will be bidding for another medal in the women's heptathlon.
British Athletics performance director Neil Black said: "Given the standard of performances from British athletes this season, and the strength in depth we possess in several events, finalising the team was far from easy and there were some tough decisions to make.
"In the 72 athletes, I truly believe we have selected the strongest team possible to compete for medals on the global stage.
"The team is full of world-class athletes who over the past two years since we were hosts in London have proven that they belong on the global stage."
Black paid tribute to Martyn Rooney, who has been named in the seven-man squad for the men's 400m relay.
"Special mention needs to go to Martyn Rooney, who is competing at his eighth World Championships, a truly remarkable feat for a great athlete," Black added.
