Jailed Pussy Riot star Nadezhda Tolokonnikova will serve out her two-year sentence in full after an appeal court threw out her bid for freedom on Friday (26Jul13). Tolokonnikova, who was locked up last year (12) along with bandmates Maria Alekhina and Yekaterina Samutsevich, took her fight for parole to Mordovia's Supreme Court after it was turned down by a lower court earlier this year (13). The case came before judges on Friday, but Tolokonnikova's appeal against the ruling was thrown out because she has refused to apologise for her crime. The three Pussy Riot members were sentenced to two years in prison for staging a protest against Russian President Vladimir Putin at a church in Moscow last year. Samutsevich was freed in October (12) when her sentence was commuted, but Alekhina's bid for parole was rejected earlier this week (beg22Jul13). She and Tolokonnikova will now serve their sentences in full and are not due for release until August, 2014. This week's (beg22Jul13) appeal rulings come just days after a group of the most famous musicians in the world signed an open letter calling for the women's release. Adele, Radiohead, One Direction, U2, Sting, Madonna, Sir Elton John, Sting, Coldplay, Sir Paul McCartney, Lily Allen, Bob Geldof and Bruce Springsteen were among a huge number of artists who all signed the Amnesty International message calling for Russian authorities to free the rockers.
