As the Olympics gets underway, Michael Morpurgo says we need to take care that the event doesn't stray too far from the ideals of the Olympics and the Paralympics.

'The announcement this year,' writes Michael, 'that athletes at the Olympics will, for the first time, be awarded prize money - $50,000 for each gold medal - sets a precedent in the Games' 128 year history.'

But, he says, 'over the next two weeks, I should like to think that the Olympics will uphold the spirit that has sustained the Games for so long... that the glory is in the laurel wreath or the medal, that the heroism is in the triumphs and disasters.'
