The British plot to overthrow Italy's elected government had the Communist won in the 1970's

An Italian researcher discovered among recently declassified papers in London that in the 1970's the British government actively sought to stage a putsch in Italy had the Italian Communist Party, that country's second largest party, won the elections. They did, and so the plans were scrapped.
For readers with a longer memory or a finer sense of history, in Europe, and certainly in Italy, it was widely feared that the CIA, MI6, and members of the Italian right-wing, including the resurrected Fascist party, were plotting to overthrow the elected government, even were it the corrupt Christian Democratic led team in office. It also was a time when the Red Brigade flourished fighting a dirty war against the establishment, partly fearing the return of a Mussolini styled fascist rule. It was a time that the Italian cineaste Pasolini made his cinematographic, difficult masterpiece, 'Salo or the 100 days of Salo'. [Salo was the fascist republic that the Germans set up in northern Italy after Mussolini fled when the Americans were fighting up the Italian peninsula. And for 100 days, this phantom fascist joke reigned till the Nazis were defeated. Mussolini and his mistress were killed and then hung up on lamp posts.] It was the time Aldo Moro was kidnapped but the government refused to rescue him, and as a result his body was found in a boot of an automobile. Overriding this confusion and spectre of a putsch from the right, the sad events of Italy in the 1970's played out. What was so fearful about the CPI, a party whose great man Palmiro Togliatti [whose great admirer was the aristocratic Luchino Visconti] made the historic compromise with the bourgeois party, and had toned down the message of war and revolution. That made no difference to the CIA, MI, nor the Italian right wing diehards, for them Italy had become the epicentre of the cold war and the battlefield to thwart Moscow's aim. They misread history, but the CPI did not win at the polls, so the plan was scrapped. A footnote, the British consulted that paragon of virtue and democracy Henry Kissinger on the matter. What a logical choice! He has engineered a coup against the democratically elected mild Socialist government of Allende, bringing thereby to power another paragon of virtue Pinochet whose long rule left a wake of bodies and ill fortune to Chile.
