The show to be broadcast worldwide on the web starting in July will see 30 participants, 15 of them women, ditched on a large island in the Ob River, the seventh longest in the world, chasing a 100 million rouble ($1.7 million) prize on a nine month survival mission in winter temperatures as low as minus 50C.

Called Game2:Winter, the reality TV programme has quietly dropped a shocking rule that stated: 'Everything is allowed. Fighting, alcohol, murder, rape, smoking, anything.'

When asked if he will intervene if there is 'physical violence, rape, a murder', organiser Yevgeny Pyatkovsky, 35, a Novosibirsk millionaire, told The Siberian Times: 'No we won't. I am pretty sure there will be fights, and more. We are not scared of negative reaction if that happens either.'

He insisted it would be made clear to the international participants ahead of the show 'that punishment will follow according to the Russian Criminal Code'. In other words, any action would be for the police or other law enforcement agencies only, not the show's organisers.
