The daughter of the jailed Ukrainian opposition leader Yulia Tymoshenko has urged David Cameron to withdraw President Viktor Yanukovych's invitation to next month's Olympics.The British government is boycotting the group stage of the Euro 2012 football championship in Ukraine in protest at the deteriorating human rights situation and the jailing of Tymoshenko, the country's former prime minister, last year.But in an interview with the Guardian before Tuesday's Ukraine v England game, Eugenia Tymoshenko said the boycott by the UK and other EU countries had been ineffective. Yanukovych had ignored it, she said, with prosecutors indicating on Monday that Tymoshenko would additionally be charged with murder.
