London 2012 will offer a taste of great sport, great business and great culture. More importantly, its legacy won’t be limited to Britain. The hosts are ready for some special times, writes UK Prime Minister David Cameron.

In exactly 100 days, the 2012 Olympics will open in London and it will be a spectacle for the world to see. We wish to share the fantastic Olympic and Paralympic Games with the people of India, and thus we welcome you to the greatest show on the earth.

These Games, and the summer in its entirety, will be a proud moment for Britain. We will not only be staging what we are determined to make the best Olympics ever, but also be celebrating 60 years of Her Majesty the Queen’s reign as she becomes the second-longest serving monarch on the planet. These are special times for our country and we want to share it with the people of India.

I’m certain that Britain will be at its very best for the Olympics. We’ve built brilliant new venues, we’ve got the city pumping more than ever, and we’ve got our transport systems well in place. Everything is in readiness towards welcoming the world to this great spectacle.

What will London 2012 offer? In my view, these Games are about two vital factors. First, sport will most definitely be at the heart of this great competition. World records will be broken, memories will be created, and new friendships will have begun during the Games themselves. But once the events are over and the medals are handed out, I am determined that these Olympics will go on to change our lives for the better.

This legacy is of paramount importance. When we won our bid, Jacques Rogge, the president of the International Olympic Committee, spoke of the “distinctive magic” that the UK will breathe into the 2012 Games, and we are going all out to keep the magic as distinct as ever. As the only city to have been awarded the Olympics thrice, we will hold the Games in great tradition.

In 1908, the modern Olympics came of age in London, with all athletes being paraded under their national flags for the first time. The route of the marathon, spaced over 26 miles and 385 yards, was set such that the race would start at Windsor Castle and finish in front of the stadium’s Royal Box, and this is the distance that has been used worldwide ever since.

Then in 1948, the Games took place in the shadow of the devastating World War. Yet London succeeded in bringing countries together to celebrate the Olympic ideals of friendship and international community. More importantly, London 1948 created new opportunities for women in sport, pioneered the Olympic volunteering movement, and laid the foundations for the modern Paralympics.

This summer, when the athletes and visitors arrive, they will find a whole new quarter of London around the Olympic Park. The location has been a powerhouse of regeneration, and when the Games are over, it will become the site of new homes, businesses and jobs.

We have pioneered new methods of design and construction, using low carbon technologies to make London 2012 the first truly sustainable Games. Also, by investing in new sporting facilities and establishing a new School Games in schools all around the country, we’re inspiring new generations of young people to experience the joys and benefits of sport.

The legacy of London 2012, however, will not just be limited to Britain. The International Inspiration programme is creating opportunities for more than 12 million people in 20 countries around the world. Not only is it allowing more of the youth to enjoy sport today, but also helping change the way these countries promote sport in school and across society.

It is a great example of how determined we are to ensure that every nation, and not just the UK, can be part of the inspiration that is 2012. Thus, I want these Games to be more than just welcoming athletes to London for a single summer. We wish to build new, lasting ties between India and Britain.

If you are a student, London 2012 is a chance to know more about a country which has four of the top ten universities in the world, and more than 75 Nobel laureates for science and technology alone. If you are an entrepreneur or investor, London 2012 is a chance to discover potential opportunities in a country that has the fewest entrepreneurial barriers to entrepreneurship in the world.

If you are a tourist or a visitor, London 2012 is a chance to experience Britain’s unique blend of the old and the new; the history and heritage of our castles, landscapes and royal houses alongside the cutting edge culture of our music, art, theatre and fashion.

Great sport. Great business. Great culture. The London 2012 Games await you.
