Prime Minister Vladimir Putin of Russia has accepted his party's nomination for president in elections next year.
Mr Putin has already served two terms as president from 2000 to 2008.
He was confirmed on Sunday as the candidate during a rally of his United Russia party in Moscow. The event was broadcast live on television.
Parliamentary polls will be held on 4 December, followed by the presidential ballot in March.
Mr Putin, 59, was constitutionally obliged to leave the presidency after serving two consecutive four-year terms.
The constitution now permits him to serve two more consecutive terms of six years, which could see him stay president until 2024.
President Dmitry Medvedev is expected to take over the prime minister's post.
