Volen Siderov

In September 2019, Siderov announced his resignation from Bulgaria's National Assembly, in order to run for the post of mayor of Sofia, Bulgaria's capital and largest city, in the 2019 Bulgarian local elections.

In September 2018, Siderov met with Israeli MK Oren Hazan, a member of the Likud party, during the latter's visit to Bulgaria. Hazan defended the meeting by noting that Siderov "said he apologized for what he had said" about the Holocaust in the past, and Hazan then "told him he needed to do it publicly".

Siderov reportedly espouses anti-Masonic conspiracy theories, claiming that Masons control the world through puppet regimes, international organizations, and the press. According to Siderov, these forces seek to commit genocide against Bulgarian people. Attack opposes the membership of Bulgaria in NATO; Siderov has declared that the people were lied to, that Bulgaria would be the safest place by then Bulgarian Minister of Foreign Affairs—Solomon Pasi—but the result was reducing the Bulgarian army to 20,000 troops and in necessity Bulgaria would be defenseless as the Turkish government wants. He compared the accession of Bulgaria to NATO as a new signing of the Treaty of Neuilly-sur-Seine, considered as humiliating treaty for Bulgaria, signed after World War I. Although the party is ambivalent on Bulgaria's European Union membership, it has demanded a revision of some of the previous agreements (e.g. the resolution on shutting down the Kozloduy Nuclear Power Plant near the Danube), it claims that those who signed the EU membership, referring to Meglena Kuneva and others, are national traitors, not because of the EU membership itself, but because of the "anti-Bulgarian" agreements, on which it is signed. Siderov expressed respect to the Russian president Vladimir Putin, by visiting him on foot for his 60th birthday on 7 October 2012. On 8 March 2013 Siderov paid tribute to the deceased president of Venezuela Hugo Chavez at the Bolivarian republic's embassy in Sofia, where he called the revolutionary an 'example for the Bulgarian patriots as a statesman'.

In February 2007, the newspaper 168 Hours published claims that the Movement for Rights and Freedoms has paid BGN 1.6 million to "Attack". On 23 February 2007 Volen Siderov appeared in the offices of 168 Hours, and asked for an explanation, which was not provided. Attack is suing the newspaper for libel.

Siderov ran for President in the 2006 presidential election. In the first round on 22 October he received 21% of the vote and qualified for the runoff on 29 October against incumbent Georgi Parvanov, who had 65%. Parvanov was not declared the winner after the first round because, in accordance with Bulgarian electoral law, at least 50% of all registered voters had to take part in the first round for that. Mainstream right-wing parties in Bulgaria (the UDF and the DSB) refused to back any of the candidates, despite appeals by many observers, notably by fellow conservative and European People's Party chairman Hans-Gert Pöttering, to support Parvanov (the situation was commonly compared with the way French left voters supported mainstream right-wing candidate Jacques Chirac against far-right Jean-Marie Le Pen in 2002). The centrist National Movement for Simeon II ultimately decided to back Parvanov. Meanwhile, some far left formations called their sympathizers to support Siderov. In the second round he lost, receiving about 24% of the vote.

During the June 2005 parliamentary elections, already a popular TV host, Siderov organised and led the party "Attack", named after his talk show. The party won 8.14% (296,848 votes) of the total vote, thus becoming the 4th largest party in parliament. In the 2009 elections Attack won 9.4% (395,000 votes) of the total vote.

During the 2003 local elections Siderov ran for mayor of Sofia on the ticket of the marginal National Association-BZNS Party. He received 1,728 votes, or 0.45%. That attempt passed largely unnoticed for the general public.

Siderov and his party "Attack" were among the few Bulgarian political forces that opposed the closing of the four units of the Kozloduy Nuclear Power Plant. Units 1 and 2 were taken shut down in the end of 2003 and units 3 and 4 were taken out of operation in the final hours of 2006, immediately prior to the country's accession to the European Union.

In 2002 Siderov was invited to a controversial anti-globalisation conference in Moscow where he associated with people like Ahmed Rami and David Duke.

At one point he was appointed deputy editor-in-chief of Monitor, a newspaper of a political orientation that could be described as nationalist and conservative. In 2000, Siderov was presented with the award of the Union of the Bulgarian Journalists. Later, he came to be the host of Attack, a talk show on the Bulgarian cable TV channel "SKAT".

After the fall of Communism, Siderov became a member of the newly established Movement for Human Rights. During the fall of 1990, he became the editor-in-chief of Democracy (Bulgarian: Демокрация ), the official newspaper of the Union of Democratic Forces (Siderov played a major role in establishing the paper as the official publication of the right-wing party).

Volen Nikolov Siderov (Bulgarian: Волен Николов Сидеров ; born 19 April 1956) is a Bulgarian politician and chairman of the nationalist party Attack. He has been the editor of numerous newspapers and has authored five books.

Siderov was born in 1956 in Yambol, Bulgaria. He received an undergraduate degree in Applied Photography in Sofia, and before the fall of Communism in 1989, worked at the National Literature Museum as a photographer. His brother, Dr. Plamen Siderov, is a mathematician and lectures at Sofia University.

Attack insists on the cancellation of Treaty of Neuilly-sur-Seine and the returning of the Western Outlands to Bulgaria, annexed by Yugoslavia after the First World War, which consists of the regions of Dimitrovgrad and Bosilegrad in Serbia, whose population according to the Serbian national census is predominantly ethnic Bulgarian, and of the region of Strumica in Republic of Macedonia. Siderov said that the treaty is invalid, because it was signed with Yugoslavia in 1919, a vanished state, and does not refer to the present-day Serbia or to the Republic of Macedonia and should be cancelled.
