"Six years on from London 2012, it is fantastic to demonstrate such a strong major events legacy from the Olympic and Paralympic Games and our work in this area has significantly enhanced our international reputation," Esther Britten, UK Sport's head of major events, said.
"The significant economic impact comes on top of the benefits athletes receive when competing on home soil in addition to the phenomenal opportunities spectators and volunteers enjoy when experiencing live sport.
"Every London 2012 venue has hosted world-class competition since the Games while they have also been open to the general public, allowing people of all ages to use the same arenas as their inspirational Olympic and Paralympic heroes.
"London 2012 established the UK as a world-leading host of major sporting events and, as the Government's specialist major events agency, and with support from the National Lottery, we will continue bringing some of the world's top sporting events to London and the rest of the UK."
UK Sport revealed the 2017 International Association of Athletics Federations World Championships at the Olympic Stadium provided the greatest economic impact of their National Lottery investment.

"We congratulate London and UK Sport on continuing to deliver an impactful Games legacy that is adding value to the city and its citizens six years on from hosting the Games," Christophe Dubi, International Olympic Committee (IOC) Olympic Games executive director, said.
"This is a great example of how the Olympic Games can transform lives and provide diverse long-term benefits for a city for years and decades to come."
