Garry Kasparov, former chess grandmaster and leader of the Other Russia Movement, was interrupted by a penis-shaped helicopter during a speech to his coalition.

The Moscow Times reported today that the incident was a prank caused by “a couple of pro-Kremlin Young Russia activists” who intended to mock the anti-Putin gathering which brought together over 500 followers and press representatives.

His listeners, who ranged from Communists to human rights supporters, were part of Kasparov’s attempt to unite the opposition to the Kremlin with the goal of the “restoration of democracy”, Associated Free Press understands.

Kasparov interruption Minutes into Kasparov’s speech, a low hum attracted both attention and laughs when the obscene aircraft buzzed over the heads of camera-wielding journalists.

Many of Other Russia’s pre-election campaigns were marred by similar events, but none were as audacious as the most recent bid, which was smashed out of the air by a heavy-handed and humourless party supporter.

The meeting was marked with fierce comments before the farce ensued, with Kasparov blaming the Putin-backed government for “taking the country to the brink of national disaster”.

Tempers heightened when a young woman called Samara read from the group’s founding charter before adding: "We should spit in the face of tsars Putin and Medvedev."

The comments and flying penis follow the controversial national election in March, in which Putin’s candidate, former Deputy Prime Minister Dmitry Medvedev, received 70.3% of the vote.

The Organization for Security and Co-operation in Europe (OSCE) refused to monitor the election due to what they believed to be “severe restrictions on its observers by the Russian government”.
