Question: Who refuted the statement that the Queen was critical of the organization that uses the Anthem of Europe?

full_context: Document 1: Anthem of Europe: "Anthem of Europe" is the anthem used by the Council of Europe to represent Europe as a whole and the European Union. It is based on "Ode to Joy" from the final movement of Beethoven's 9th Symphony composed in 1823, and is played on official occasions by both organisations.
Document 2: The Sun (United Kingdom): Despite its initial opposition to the closures, until 1997, the newspaper repeatedly called for the implementation of further Thatcherite policies, such as Royal Mail privatisation,[verification needed] and social security cutbacks, with leaders such as "Peter Lilley is right, we can't carry on like this",[verification needed] The paper showed hostility to the EU and approval of public spending cuts, tax cuts, and promotion of right-wing ministers to the cabinet, with leaders such as "More of the Redwood, not Deadwood".
Document 3: The Sun (United Kingdom): In exchange for Rupert Murdoch's support, Blair agreed not to join the European Exchange Rate Mechanism – which John Major had withdrawn the country from in September 1992 after barely two years. Cabinet Minister Peter Mandelson was "outed" by Matthew Parris (a former Sun columnist) on BBC TV's Newsnight in November 1998. Misjudging public response, The Sun's editor David Yelland demanded to know in a front page editorial whether Britain was governed by a "gay mafia" of a "closed world of men with a mutual self-interest". Three days later the paper apologised in another editorial which said The Sun would never again reveal a person's sexuality unless it could be defended on the grounds of "overwhelming public interest".
Document 4: Symphony: At the beginning of the 19th century, Beethoven elevated the symphony from an everyday genre produced in large quantities to a supreme form in which composers strove to reach the highest potential of music in just a few works. Beethoven began with two works directly emulating his models Mozart and Haydn, then seven more symphonies, starting with the Third Symphony (``Eroica '') that expanded the scope and ambition of the genre. His Symphony No. 5 is perhaps the most famous symphony ever written; its transition from the emotionally stormy C minor opening movement to a triumphant major - key finale provided a model adopted by later symphonists such as Brahms and Mahler. His Symphony No. 6 is a programmatic work, featuring instrumental imitations of bird calls and a storm; and, unconventionally, a fifth movement (symphonies usually had at most four movements). His Symphony No. 9 includes parts for vocal soloists and choir in the last movement, making it a choral symphony.
Document 5: Symphony No. 5 (Beethoven): Beethoven was in his mid-thirties during this time; his personal life was troubled by increasing deafness. In the world at large, the period was marked by the Napoleonic Wars, political turmoil in Austria, and the occupation of Vienna by Napoleon's troops in 1805. The symphony was written at his lodgings at the Pasqualati House in Vienna. The final movement quotes from a revolutionary song by Claude Joseph Rouget de Lisle.
Document 6: Ode to Joy: "Ode to Joy" (German: ), is an ode written in the summer of 1785 by German poet, playwright, and historian Friedrich Schiller and published the following year in "Thalia". A slightly revised version appeared in 1808, changing two lines of the first and omitting the last stanza.
Document 7: The Sun (United Kingdom): Critics stated that both The Sun and Lord Kilbracken cherry-picked the results from one specific study while ignoring other data reports on HIV infection and not just AIDS infection, which the critics viewed as unethical politicisation of a medical issue. Lord Kilbracken himself criticised The Sun's editorial and the headline of its news story; he stated that while he thought that gay people were more at risk of developing AIDS it was still wrong to imply that no one else could catch the disease. The Press Council condemned The Sun for committing what it called a "gross distortion". The Sun later ran an apology, which they ran on Page 28. Journalist David Randall argued in the textbook The Universal Journalist that The Sun's story was one of the worst cases of journalistic malpractice in recent history, putting its own readers in harm's way.
Document 8: The Sun (United Kingdom): During the campaign for the United Kingdom general election, 2010, The Independent ran ads declaring that "Rupert Murdoch won't decide this election – you will." In response James Murdoch and Rebekah Wade "appeared unannounced and uninvited on the editorial floor" of the Independent, and had an energetic conversation with its editor Simon Kelner. Several days later the Independent reported The Sun's failure to report its own YouGov poll result which said that "if people thought Mr Clegg's party had a significant chance of winning the election" the Liberal Democrats would win 49% of the vote, and with it a landslide majority.
Document 9: Brexit: Brexit (/ ˈbrɛksɪt, ˈbrɛɡzɪt /) is the impending withdrawal of the United Kingdom (UK) from the European Union (EU). In a referendum on 23 June 2016, 51.9% of the participating UK electorate voted to leave the EU; the turnout was 72.2%. On 29 March 2017, the UK government invoked Article 50 of the Treaty on European Union. The European Union (Withdrawal) Act 2018 declares ``exit day ''to be 29 March 2019 at 11 pm UTC.
Document 10: The Sun (United Kingdom): On 9 March 2016, The Sun's front page proclaimed that Queen Elizabeth II was backing "Brexit", a common term for a British withdrawal from the European Union. It claimed that in 2011 at Windsor Castle, while having lunch with Deputy Prime Minister Nick Clegg, the monarch criticised the union. Clegg denied that the Queen made such a statement, and a Buckingham Palace spokesperson confirmed that a complaint had been made to the Independent Press Standards Organisation over a breach of guidelines relating to accuracy.
Document 11: Symphony No. 5 (Beethoven): While such resemblances sometimes occur by accident, this is unlikely to be so in the present case. Nottebohm discovered the resemblance when he examined a sketchbook used by Beethoven in composing the Fifth Symphony: here, 29 bars of Mozart's finale appear, copied out by Beethoven.
Document 12: Ode to Joy: ``Ode to Joy ''(German:`` An die Freude'' (an diː ˈfʁɔʏdə), first line: ``Freude, schöner Götterfunken '') is an ode written in the summer of 1785 by German poet, playwright, and historian Friedrich Schiller and published the following year in Thalia. A slightly revised version appeared in 1808, changing two lines of the first and omitting the last stanza.
Document 13: Hymne an Deutschland: Its lyrics were written by Rudolf Alexander Schröder in 1950. Hermann Reutter composed its tune after Carl Orff, whom Heuss wanted to have as composer, had rejected the request and suggested Reutter instead. Heuss’ attempts failed, and in 1952 he and Chancellor Adenauer recognized the "Deutschlandlied" as the new national anthem, with only the third stanza being sung on official occasions.
Document 14: Classical music: The "standard complement" of double winds and brass in the orchestra from the first half of the 19th century is generally attributed to Beethoven. The exceptions to this are his Symphony No. 4, Violin Concerto, and Piano Concerto No. 4, which each specify a single flute. The composer's instrumentation usually included paired flutes, oboes, clarinets, bassoons, horns and trumpets. Beethoven carefully calculated the expansion of this particular timbral "palette" in Symphonies 3, 5, 6, and 9 for an innovative effect. The third horn in the "Eroica" Symphony arrives to provide not only some harmonic flexibility, but also the effect of "choral" brass in the Trio. Piccolo, contrabassoon, and trombones add to the triumphal finale of his Symphony No. 5. A piccolo and a pair of trombones help deliver "storm" and "sunshine" in the Sixth. The Ninth asks for a second pair of horns, for reasons similar to the "Eroica" (four horns has since become standard); Beethoven's use of piccolo, contrabassoon, trombones, and untuned percussion—plus chorus and vocal soloists—in his finale, are his earliest suggestion that the timbral boundaries of symphony should be expanded. For several decades after he died, symphonic instrumentation was faithful to Beethoven's well-established model, with few exceptions.
Document 15: Elizabeth II: In 1956, the British and French prime ministers, Sir Anthony Eden and Guy Mollet, discussed the possibility of France joining the Commonwealth. The proposal was never accepted and the following year France signed the Treaty of Rome, which established the European Economic Community, the precursor to the European Union. In November 1956, Britain and France invaded Egypt in an ultimately unsuccessful attempt to capture the Suez Canal. Lord Mountbatten claimed the Queen was opposed to the invasion, though Eden denied it. Eden resigned two months later.
