Question: What newspaper described a man who says Villa Sellgren is owned by Vladimir Putin as "the man Vladimir Putin fears most"

Context paragraphs:
Vera Putina: Vera Putina (Russian: Вера Николаевна Путина ; born 6 September 1926) is a woman who has since 1999 stated that Vladimir Putin ("Vova") is her lost son.  The woman's claims contrast with Putin's official biography, which states that Putin's parents died before he became president. " The Telegraph" concluded that while the woman might be simply wrong or part of a public relations effort, the story "identifies the holes in the known story of Mr Putin's past".  The official story is that Putin's parents were already in their forties when Putin was born, which leaves a gap of over fifteen years since the births of their previous sons, Oleg and Viktor, neither of whom survived childhood.  Details of the first ten years of Putin's life are scarce in his autobiography, especially when compared with other world leaders."

Villa Sellgren: Villa Sellgren is a house and estate on Lodochny Island in the Gulf of Finland of the Baltic Sea.  It was designed by the Finnish architect Uno Ullberg and completed in 1913.  The house was a location used in the shooting of a Russian version of Arthur Conan Doyle's "His Last Bow" in 1986.  It was part of national forest reserves until 2012 when it was rezoned to allow construction.  According to Russian opposition leader Alexei Navalny, the house is owned by Vladimir Putin through friends.

Putin's Kleptocracy: Putin's Kleptocracy: Who Owns Russia?  is a 2014 book by Karen Dawisha.  Published by Simon & Schuster, it chronicles the rise of Vladimir Putin during his time in Saint Petersburg in the 1990s.  In the book, Dawisha exposes how Putin's friends and coworkers from his formative years have accumulated mass amounts of wealth and power.  Although Putin was elected with promises to rein in the oligarchs who had emerged in the 1990s, Dawisha writes that Putin transformed "an oligarchy independent of, and more powerful than, the state into a corporatist structure in which oligarchs served at the pleasure of state officials, who themselves gained and exercised economic control... both for the state and for themselves."  As a result, 110 individuals control 35% of Russia's wealth, according to Dawisha.  Whereas scholars have traditionally viewed Putin's Russia as a democracy in the process of failing, Dawisha argues that "from the beginning Putin and his circle sought to create an authoritarian regime ruled by a close-knit cabal... who used democracy for decoration rather than direction."

Mikhail Fradkov's First Cabinet: Mikhail Fradkov's First Cabinet (March - May 2004) was a cabinet of the government of the Russian Federation during the presidential election of 2004, preceded by the cabinet of Mikhail Kasyanov, who had been dismissed by President Vladimir Putin on February 24, 2004, and followed by Mikhail Fradkov's Second Cabinet immediately after Vladimir Putin's second inauguration.  It was led by Prime Minister Mikhail Fradkov, proposed by President Vladimir Putin for the approval by the State Duma on March 1, 2004.  On March 5 Fradkov was approved by the State Duma and appointed Prime Minister by the President.  Other 16 ministers of the cabinet were appointed by presidential decrees on March 9.  Seven of the ministers occupied the same positions in Mikhail Kasyanov's Government: Yury Chaika, Alexey Gordeyev, German Gref, Sergei Ivanov, Viktor Khristenko, Alexey Kudrin, and Sergei Shoigu.  The cabinet underwent no reshuffles and resigned on May 7.  It was a temporary cabinet, as Russian legislation stipulates that a new government has to be formed in the beginning of a new presidential term, so the ministers remained acting and were reappointed with minor changes as Mikhail Fradkov's Second Cabinet few days later.

Putin khuilo!: "Putin – khuilo!"  (Ukrainian: Пу́тін - хуйло́ ; ] , Russian: Пу́тин - хуйло́ ; ] , a commonly used English translation: "Putin is a dickhead") is a Ukrainian- and Russian-language slogan deriding Russian President Vladimir Putin.  The slogan was originated in Ukraine in 2014 having grown from a football chant first performed by FC Metalist Kharkiv ultras in March 2014 on the onset of the Russian annexation of Crimea and military intervention in Ukraine.

Other 28 ministers were appointed by the President on May 18–20.  Only six of them were new to the government: Gennady Bukaev, Alexander Dondukov, Alexander Gavrin, German Gref, Alexey Kudrin and Igor Shuvalov.
