The day, which will open National School Sport Week in England and Wales, will give thousands of young people in schools across the UK the chance to take part in the final UK-wide Get Set event before the London 2012 Games begin.

The plans for London 2012 World Sport Day were announced today at the Copper Box in the Olympic Park. Get Set Network schools Ripple Primary School and Jo Richardson Secondary, both from Barking and Dagenham, took part in the announcement as well as Olympic gold medallist Jonathan Edwards, Team GB athletes Zoe Smith and Charlie Walker, Fijian athlete Sisilia Nsigia Rasokisoki and New Zealand athlete Jonathan Paget.

Students from schools and colleges will be encouraged to celebrate the athletes and cultures of the world on the day in a variety of ways including staging their own World Sport Day opening ceremony and profiling the sports, music, dance, languages, flags and food of the world.

London 2012 will provide resources to schools through the official education programme Get Set, including tips from the London 2012 Ceremonies team of producers on how to host an opening ceremony for World Sport Day. Schools can download a planning guide to help them to prepare for their day at www.london2012.com/worldsportday

London 2012 will also be releasing and promoting new resources every month to help schools plan their day and decorate their school for the celebrations. Schools can request their free event pack on the World Sport Day website; the pack is full of branded materials and decorations, with schools in the Get Set network receiving access to extra materials and opportunities.

Chair of London 2012,  Seb Coe said: "With the Games almost here, World Sport Day presented by Lloyds TSB is a fantastic opportunity to bring the young people of the UK together on one day to celebrate our amazing athletes from all over the world, and their nations and cultures. The day will showcase all the work young people are doing on the teams they have been supporting – whether as a class, a year group or a whole school community. We want to encourage schools to involve parents, governors, members of the wider community and other local schools to join together on 25 June for what will be a great celebration of sport and cultures of the world."

Team GB athlete Zoe Smith said: "The Games are the world’s greatest festivals of sport and London 2012 World Sport Day is a great way to celebrate how London 2012 will bring athletes together from so many different cultures. I have always been inspired by the Games, mainly because it provides a platform to learn about athletes, cultures, food and language from all over the world. I’m delighted to be part of World Sport Day and to see how it will help young people to learn about these different elements, as well as getting excited about the Games."
