Do big events sponsors have too much influence?
Sports fans who want to buy tickets by card for the London 2012 Olympics will only be able to use the Visa payments system. Are such restrictions acceptable?
The restrictions are part of the sponsorship deal struck between Visa and the Olympic and Paralympic Games. Visa cards will be the only ones accepted at shops and cash machines at Olympic venues. The Office of Fair Trading said it was looking into the matter.
It is the latest example of the tight control exerted by sponsors over events after paying for sponsorship rights, including the case of the young women in orange mini dresses who were accused of trying to promote a Dutch beer at the World Cup, breaking strict Fifa marketing rules.
How much power should sponsors have over event arrangements? Should there be more competition at events? Were you aware such agreements existed?
