The Russian President Dmitry Medvedev has marked the raising of the Olympic flag over Sochi, the venue for the 2014 Winter Games, by threatening criminal proceedings against his country's sporting administrators.
Russia endured their worst ever Winter Olympics in Vancouver last month, winning fewer gold medals than the Netherlands. The government has responded, amid allegations of corruption, by ordering an investigation into how a pre-Games budget of £78m was spent.
Mr Medvedev said: "The audit chamber is checking the use of budget funds aimed at preparing for the Vancouver Olympics. According to the results, we will decide what to do with the [report] – just to hear it or send it to the prosecutor's office."
Since the Games a number of leading officials have resigned following a public outcry over their sixth place in the medals table, including the Deputy Sports Minister.
