  In his later years, Stalin was in poor health. He took increasingly long holidays; in 1950 and again in 1951 he spent almost five months on holiday at his Abkhazian dacha. Stalin nevertheless mistrusted his doctors; in January 1952 he had one imprisoned after they suggested that he should retire to improve his health. In September 1952, several Kremlin doctors were arrested for allegedly plotting to kill senior politicians in what came to be known as the doctors' plot; the majority of the accused were Jewish. He instructed the arrested doctors to be tortured to ensure confession. In November, the Slánský trial took place in Czechoslovakia as 13 senior Communist Party figures, 11 of them Jewish, were accused and convicted of being part of a vast Zionist-American conspiracy to subvert Eastern Bloc governments. That same month, a much publicised trial of accused Jewish industrial wreckers took place in Ukraine. In 1951, he initiated the Mingrelian affair, a purge of the Georgian branch of the Communist Party which resulted in over 11,000 deportations.
  
  From 1946 until his death, Stalin only gave three public speeches, two of which lasted only a few minutes. The amount of written material that he produced also declined. In 1950, Stalin issued the article " Marxism and Problems of Linguistics ", which reflected his interest in questions of Russian nationhood. In 1952, Stalin's last book, Economic Problems of Socialism in the USSR, was published. It sought to provide a guide to leading the country after his death. In October 1952, Stalin gave an hour and a half speech at the Central Committee plenum. There, he emphasised what he regarded as leadership qualities necessary in the future and highlighted the weaknesses of various potential successors, particularly Molotov and Mikoyan. In 1952, he also eliminated the Politburo and replaced it with a larger version which he called the Presidium.
