Lord Sebastian Coe has confirmed that London will bid to be the host of 2017 World Athletics Championships.
The 54-year-old will accompany UK Athletics in South Korea later this month to submit the plans.
"The IAAF and the athletics family have been unwavering in their support for an Olympic legacy," said Coe.
"A successful bid would say thank you for that constant support by delivering a fantastic IAAF World Championships in London that will help drive more young people into the sport."
A decision is expected to be made in November.
