How the separatists delivered Crimea to Moscow

* New leader named while gunmen occupy regional assembly

* Openly separatist Aksyonov won just 4 percent of vote in 2010

* Nicknamed "The Goblin" during business career in 1990s

* Some politicians cast doubt over legitimacy of parliament vote

SIMFEROPOL, Ukraine, March 12 (Reuters) - Within a week of its building being taken over by armed gunmen last month, the regional parliament in Crimea was voting in favour of the Ukrainian region becoming part of Russia.

How that was achieved under the leadership of Sergei Aksyonov, 41, a Russian separatist whose political party won 4 percent of the vote at the parliamentary election in 2010, was a master class in vote rigging and intimidation, according to several opposition lawmakers.

"It was all a great spectacle, a tragic spectacle," said Leonid Pilunsky, one of a number of regional lawmakers who say a vote behind closed doors to install Aksyonov was fixed and key decisions were taken before anyone could respond.

Moscow says Crimea is in the grip of a home-spun uprising, a popular response to the revolt in Kiev which ousted Ukraine's Russian-backed President Viktor Yanukovich.

But for the authorities in Kiev and local politicians still loyal to Ukraine, the rapid pace of events were evidence of a carefully orchestrated campaign from Moscow.

Moscow denies any role in installing Aksyonov, who is known from his business days by the nickname "The Goblin". But even those close to the Kremlin say Russia picked him.

"Moscow always bet on Yanukovich. But after the coup in Kiev on Feb. 22 ... Moscow decided it needed to back the secession of Crimea from Ukraine. Then they looked for who could be its leader," said Sergei Markov, a political analyst sympathetic to the Kremlin who often explains its workings abroad.

"They chose Aksyonov."

ENTER THE GOBLIN

The day before the takeover of Crimea began, on Feb. 26, the region's parliament met to debate holding a referendum on loosening ties with Kiev. The atmosphere was volatile.

In the four days since Yanukovich had fled Kiev, pro-Russian groups had been signing up volunteers to self-defence militias, spurred by Russian television reports that armed Ukrainian nationalists would descend from the capital.

While Crimea's parliamentarians met, thousands of pro-Russian demonstrators clashed outside the building with protesters supporting unity with Kiev.

The vote on the referendum was not held that day: there were not enough lawmakers to reach a quorum after Pilunsky and another opposition lawmaker refused to register as present. "They begged, appealed and threatened us," he said.
