Russia's presidential election: Q&A with Luke Harding Workers put up a pre-election poster featuring Vladimir Putin and Dmitry Medvedev in Krasnodar, Russia. Photograph: Eduard Korniyenko/Reuters With two days to go until Sunday's presidential election, all eyes turn towards Russia. There's not much suspense about who exactly is going to win: Vladimir Putin will swagger home for a third stint in the Kremlin. But the poll takes place amid an unprecedented middle-class uprising against Putin's rule, set off by allegations of fraud after December's parliamentary elections. All the signs are that this poll will be no cleaner. The Kremlin disqualified the only genuine opposition candidate - the leader of the liberal Yabloko party - from taking part; state TV has provided favourable blanket coverage of Putin; and opposition activists allege that officials and Russia's election commission are planning to stuff ballot boxes, as in the past. Massive anti-Putin demonstrations are planned for Monday. With Putin showing no willingness to step down, is Russia heading inexorably towards revolution? Can we talk about a "Russian spring," or is this - as well as being the wrong metaphor for icy Moscow - simply wishful thinking? And why does Putin want to stay in power forever? Is this, as critics suggest, the only way for Russia's leader and his team to hang on to their ill-gotten billions, in a country dubbed by US diplomats a "virtual mafia state"? The Guardian's former Moscow correspondent Luke Harding will be online for an hour today to answer your questions. Please post them below from 12.30pm, UK time. In 2011 Luke became the first western journalist to be expelled from Moscow since the cold war. This followed a long, thuggish campaign of hounding by the FSB, the KGB's murky successor agency. Luke is happy to answer all questions - but won't deal with online activists in the pay of the Kremlin, whose activities were recently revealed by the Guardian's Miriam Elder.
