Nicolas Sarkozy has told heads of major internet companies that they do not live in a parallel, moral-free universe.

The french president gave his warning at the start of the e-G8 conference that he called in Paris.

Facebook's Mark Zuckerberg, Google's Eric Schmidt and News Corp's Rupert Murdoch are among those swapping ideas at the forum.

Their conclusions will be presented to G8 leaders at Deauville later this week.
