Earlier on Friday Ukraine’s parliament overwhelmingly voted in favour of a return to the country’s 2004 constitution. <br /><br />While it means President Yanukovich will lose some power, opposition leaders were insistent the vote was only a first step. <br /><br />Addressing parliament opposition leader Arseniy Yatsenyuk declared: ‘‘The parliament is about to take a vital decision. It concerns not only the restoration of constitutional order but order in Ukraine. It is a crucial choice which will put an end to the dictatorial powers of President Yanukovich. <br /><br />‘‘It is the first step, only the first step to bring back justice and equity to our country. It is a long road before peace and stability can return to Ukraine, before rebuilding Ukraine, before bringing all those to justice, and I insist, all those who have given the illegal orders to use torture and to kill.’‘<br /><br />In addition, Ukraine’s parliament also agreed to amend the country’s criminal code. A move which could pave the way for the release of jailed opposition leader Yulia Tymoshenko. <br /><br />But, measures to bring those responsible to justice for the bloody violence are still being discussed by MPs and will need parliamentary approval first.
