Putin inaugurates new movement amid fresh protests
Russian President Vladimir Putin has taken the helm of a new political movement called the Popular Front.
Mr Putin was appointed by acclamation as head of the movement in front of a crowd of supporters.
The Front is seen by analysts as a way of strengthening Mr Putin's position as the ruling United Russia party has lost support.
It came as thousands of anti-government protesters marched in Moscow to demand Mr Putin's resignation.
Mr Putin told his supporters that he hoped the Popular Front would become a "broad public movement" and that it would help citizens with ideas for improvement see them implemented.
He also said he envisaged the movement as a watchdog that would hold those in power to account, "from the president down to the village mayor".
What does the leader of a country do when his political party is tainted by allegations of corruption and is losing support? In Russia it's very simple. He creates a new one.
The Popular Front for Russia is not officially a party. Not yet, anyway. For now, it's a pro-Putin movement. But it's set to dominate the airwaves here and the political landscape. The Popular Front has been created because the current party of power, United Russia, has grown increasingly unpopular. Critics have labelled it the party of villains and thieves. Vladimir Putin was once its leader, although never a member. More recently, the Kremlin has been trying to distance itself from it.
The staging of this congress was designed to project a positive image for the new movement to the Russian people: patriotic speeches, a standing ovation for Putin, all live on Russian TV. In his speech, President Putin made the Popular Front sound like the embodiment of people power. He'll now try to use it to reconnect the Kremlin to the Russian people and boost his support across the country.
The speech was interrupted several times by the crowd chanting "Russia!", "Putin!" and "ONF!" (the Russian initials of the movement).
After the speech a vote was conducted by Putin supporter and film director Stanislav Govorukhin.
"Looks like I am going to ask the stupidest question ever," Mr Govorukhin said. "Who will we nominate as the leader of our movement?"
The crowd replied by chanting Mr Putin's name.
"Should we vote? Are there any other candidates?" Mr Govorukhin asked.
"Vladimir Vladimirovich, congratulations. I feel for you, it is a big burden," he concluded.
Correspondents say Mr Putin hopes the new movement will shore up his support after corruption allegations that have hit the pro-Putin United Russia party.
In February, United Russia MP Vladimir Pekhtin had to resign his seat in parliament after anti-corruption campaigners accused him of owning homes in the US. Mr Pekhtin had been head of the ethics committee in the Duma, parliament's lower house.
Meanwhile, opposition activists have marched in Moscow to demand the release of prisoners detained over clashes at an anti-government protest last year.
Ten of 12 people being tried over the Bolotnaya case - named after the Moscow square where the clashes occurred in May last year - had their detention extended last week.
Police say protesters taking part in the demonstrations, which began the day before President Putin's swearing-in in May 2012, turned on them with metal bars and flagstones
Opposition leaders say the authorities provoked the clashes.
On Wednesday, several thousand protesters turned out to support the detainees, led by prominent opposition activist Alexei Navalny.
Mr Navalny is facing trial on charges of embezzling money from a regional timber firm, which he has rejected as politically motivated.
"You can't sit at home when the government begins repressions against ordinary, decent citizens of our country - people who don't want to live in this swamp, people who want to see their country thrive," activist Vitaly Zolomov told the Associated Press.
Gay rights activists also joined the march, denouncing a law passed on Tuesday by the Duma imposing heavy fines for providing information about homosexuality to people under 18.
