Boris Johnson has congratulated Tokyo on being crowned the 2020 Olympics and Paralympics host city and urged it to "savour" the celebration before the hard work starts.
A statement from the Mayor of London said:
Huge congratulations to Tokyo for winning the honour of hosting the greatest sporting spectacular on the planet.
I am sure that, like London, your great city will put on an extraordinary event. This is a magical moment of celebration to savour before the years of hard work ahead.
Staging the Olympic and Paralympic Games is a tremendous privilege that unleashes golden opportunities for the host city. London has seen its transformative effect having embedded from the outset a long lasting legacy that reaches far beyond the weeks of sporting drama.
We've been happy to welcome Rio to our city and we'll be delighted to share our experiences with Tokyo as they embark on their own journey to 2020.
