A round-up of sporting reaction to London's successful 2012 Olympic bid.
Seb's presentation was so much better than that of Paris. He and his team
have done an outstanding job. London will put on a brilliant Games. And yes, if I'm not crocked, I hope to be running there.
World marathon record-holder Paula Radcliffe on London bid leader Lord Coe
London 2012 will be a brilliant sporting event and something for us all to be very proud of.
England and Lions fly-half Jonny Wilkinson
This will be a huge opportunity for London to show they can host such an important event. It will be great to have the Games on home ground because my family, friends and all the Olympic fans can enjoy the Games here and it will really add to an already special event.
Double Olympic sailing gold medallist Ben Ainslie
The dreams have become a reality. Winning in front of your home crowd is a dream come true and winning in Sydney in 2000 was beyond my wildest imagination.
Sydney gold medallist Cathy Freeman
Happiness is a moment like this. I thought we had the best bid and that everything was in place but you still wonder. When the last name came out it blew my mind. I have never had a moment like it.
England 1966 World Cup winner Sir Bobby Charlton
I believe that sport in this country will benefit enormously with London hosting the Olympics. It's a great honour and something we can take great pride in as a country.
England cricket captain Michael Vaughan
It's just the most fantastic thing that has ever happened for British sport. Now we have to maintain the momentum not only up to 2012, but also afterwards and transform sport way beyond the Games. Seb's presentation was inspirational and the hard work of his ambassadors in the last couple of days has been sensational.
UK Athletics chief executive David Moorcroft
This will be a great boost for the whole of the country. I'm looking forward to being at the 100m final in 2012.
Manchester United and England defender Rio Ferdinand
The fact that the Olympic Games are coming to London will have positive repercussions right across these islands, and I would like to assure my UK colleagues of any support or assistance that we can provide here in Ireland.
Irish Prime Minister Bertie Ahern
I welcome the election by the IOC of an EU capital, London, as the host city for the 2012 Olympic Games. It will be up to London to prepare this most extraordinary meeting with the youth of the world and I wish London good luck.
European Commission president Jose Manuel Barroso
It's every athlete's dream to compete at an Olympic Games but to have the chance to do it in your home country is just unbelievable. Personally, I remember the fantastic atmosphere at the Commonwealth Games in Manchester and I'm delighted the British fans will get the chance to be such a major part of the best sporting event in the world.
Olympic gold medallist Mark Lewis-Francis
I couldn't believe it. I was optimistic but it did seem as if we were the underdogs. To come from behind was stunning and Seb Coe's presentation was superb. Completely illogically I've taken a moment to entertain the possibility of making a comeback. I'll be 42 but will need a new hip and a bionic surgeon.
Former Olympian Steve Backley
The work on constructing the Olympic pool in Stratford will start immediately and good progress has already been made on the design which is absolutely stunning and world class.
It is a great day for London and a great day for sport. This is destined to become a catalyst for sport and swimming to move forward in Great Britain.
British Swimming chief executive David Sparkes
The legacy of hosting this event is so significant it will transform not only athletics but British sport on the whole. The effect will not just last until the Games but will be felt beyond 2012 for many years to come.
UK Athletics chief executive Dave Moorcroft
I'm sure we'll win more medals. Imagine if I'd had that support in Athens - I might have won a gold medal! Hopefully we'll get more qualifiers and more boxers and finish higher up in the table.
I think we'll make one of the best Olympics ever.
Olympic silver medallist Amir Khan
We will now look with urgency at how the home nations could take part in the football tournaments.
The Football Association's executive director David Davies
Having the Olympic tennis tournament at the most famous tennis club in Wimbledon will undoubtedly inspire an entire generation of new tennis players. In addition the new tennis centre in the Lea Valley for the Paralympics tennis event will provide a whole new area of London with access to affordable tennis.
Lawn Tennis Association chief executive John Crowther
I am a happy man because football in England is very popular, is played at the highest level possible and they have all the stadia. It is a competition where the team must be called Great Britain but how they configure it is their problem.
Fifa president Sepp Blatter
After watching London's incredible presentation this morning, I was in no doubt that London would pull it off. We at the Millennium Stadium, Cardiff and Wales are thrilled that we will
play a part in the staging of the Olympics and I am sure everyone in Wales will
Millennium Stadium chief executive Paul Sergeant
The Olympic spirit is alive in the UK and this is a stunning triumph for us. We can now show off the best of British to the world.
Former England rugby captain Lawrence Dallaglio
British sport owes the London bid team a huge debt of gratitude and it is now
down to everyone involved in sport in the UK to get behind London and ensure
that the 2012 Games are the greatest of all time.
Welsh Rugby Union chief executive David Moffett
This decision will prove to be the launch pad for not only a successful staging of the Games, but also a significant enhancement of British culture and sport.
Rugby Football League executive chairman Richard Lewis
The hosting of the 2012 Olympics will have spectacular and long-lasting benefits for the entire country. I can assure the organisers of the London Olympics that Belfast will give them whatever support they need to make these Games the most successful in the history of the event
Belfast Lord Mayor Wallace Browne
Being so close to London, our superb National Badminton Centre in Milton Keynes will be a key facility in the preparation of our British squad - and most likely many of the other international squads in the weeks before the 2012 Games.
Badminton England chief executive Clive Ricks
London 2012 will be a huge boost for sport in the UK and will leave a lasting legacy for this country. We believe youngsters will be captivated by the spirit and will be inspired
to become participants in the entire spectrum of Olympic sports, including our
British Judo Association chairman Densign White
This will be a tremendous boost for our sport, not only in the UK, but also worldwide. It will also present us with tremendous challenges as we seek to field a team capable of competing
with the top 11 nations in one of the world's great sports.
Great Britain Basketball chairman Sandy Sutherland
As the newest recognised sport, darts, under the guidance of the British Darts Organisation, pledges its wholehearted support for the Olympic Games in London and would be proud to be considered as the host nation's 'invitation sport' in 2012.
British Darts Organisation chief Olly Croft
It is great news that the Olympic Games are coming to London. The whole of the British horse world will be delighted and the Olympics will provide equine pursuits in this country with a global showcase.
