Oscar Pistorius will become the first amputee athlete to compete at the able-bodied World Championships after being chosen to represent his country, South Africa, in South Korea.
The Championships begin in Daegu on 27 August and 24-year-old Pistorius will compete in the 400m and 4x400m relay.
Pistorius, who runs on carbon fibre legs, said: "I have dreamt for such a long time of competing in a major championships and this is a very proud moment in my life.
"It will be a great day for me when I set out on the track in Daegu and I hope to do my country proud.
"This will be the highest-profile and most prestigious able-bodied event which I have ever competed in, and I will face the highest-calibre of athletes from across the planet."
Until 2008 Pistorius was banned from competing against able-bodied athletes because the International Association of Athletics Federation (IAAF) believed he gained an unfair advantage from his “bladesâ€.
The ban was subsequently overturned by the Court of Arbitration for Sport after a lengthy legal battle with the IAAF.
The four-time Paralympic gold medallist has run faster than any British athlete over 400m this season.
