Malala Yousafzai, Mikhail Khodorkovsky, Edward Snowden, and the Belarusian political prisoners Ales Byalyatski, Eduard Lobau, and Mykalay Statkevich are among the nominees for this year's Sakharov Prize, RFE/RL said.

The prize, which is worth 50,000 euros ($65,000), is awarded every year by the European Parliament to honor defenders of human rights and freedom of expression.

The favorite to win is the Pakistani education activist and Nobel Peace Prize nominee Malala Yousafzai, who is backed by several prominent European Parliament members (MEPs) from the liberal group ALDE, as well as the two center-right groups -- the EPP and ECR.

Malala, a schoolgirl and former BBC blogger, wrote about life under Taliban pressure and her views about promoting education for girls. Last year she was shot in the head and neck by Taliban gunmen while riding a school bus, but survived the attack.

The three Belarusian nominees, all political prisoners, are also enjoying large cross-party support in the European Parliament and are backed by a large number of MEPs from neighboring Poland.

The German Green MEP Werner Schulz, together with 40 other MEPs, nominated the imprisoned former head of the oil giant Yukos, Mikhail Khodorkovsky.

Khodorkovsky, a vocal critic of Russian President Vladimir Putin, was arrested in 2003 and later convicted of tax fraud and sentenced to prison. Yukos was hit with a series of tax claims from the Russian government that totaled some $27 billion. The company was later dismantled.

In 2010, Khodorkovsky was convicted in a second case of stealing oil from his own company. He is due for release in October 2014.

The Green group and the leftist GUE/NGL party group have nominated U.S. leaker Edward Snowden, who in May revealed information about several top-secret surveillance programs run by the U.S. and British governments.

Snowden is charged by U.S. federal prosecutors with espionage and theft of government property. He has received temporary asylum in Russia.

Nominations must obtain the support of at least 40 members of the European Parliament or one political group in the chamber.

The nominees will officially be presented in the parliament's Foreign Affairs Committee on September 16.

The Sakharov Prize, named in honor of Soviet dissident Andrei Sakharov, was first handed out in 1988, with Nelson Mandela the first winner.
