Vladimir Putin's political allies won a landslide victory in a parliamentary election in Russia, near final results showed on Monday, paving the way for Putin to run for a fourth term as president in 18 months if, as expected, he chooses to do so. The ruling United Russia party, founded by Putin almost 16 years ago after he first became president, was on track to win 343 seats or 76 percent of 450 available seats in Russia's Duma, the lower house of parliament, the Central Election Commission said, after 93 percent of ballots had been counted. That is up from 238 seats in the last parliamentary election, in 2011, and would allow United Russia to change the constitution, although Putin can run again under the existing one as he was prime minister between his second and third terms. Liberal opposition parties failed to win any seats, after holding just one before. Not everything went Putin's way though. Near complete results showed turnout was around 48 percent, down from nearly 60 percent in 2011, suggesting apathy among some Russians and a softening of enthusiasm for the ruling elite. Putin, speaking to United Russia campaign staff a few minutes after polling stations closed on Sunday night, said the win showed voters still trusted the leadership despite an economic slowdown made worse by Western sanctions over Ukraine. "We can say with certainty that the party has achieved a very good result; it's won," Putin said at the United Russia headquarters, where he arrived together with his ally, Dmitry Medvedev, who is prime minister and the party's leader. — Reuters
