Markus Büchel (; 14 May 1959 â 9 July 2013) was a lawyer and politician from Liechtenstein who served as Prime Minister of Liechtenstein in 1993. Serving for just under 7 months, he is the shortest serving prime minister in Liechtenstein's history.
Büchel attended high school in Eschen from 1972 to 1975 before completing an internship in the law firm of Alfred Bühler in Vaduz. From 1981 he studied law in the University of Bern and the Ludwig Maximilian University of Munich, where he graduated in 1986.
Büchel was in office as Prime Minister of Liechtenstein from 26 May to 15 December 1993. The February 1993 Liechtenstein general election resulted in a win for the Progressive Citizens' Party (FBP), and Büchel was appointed as prime minister.
As prime minister, he co-signed the Constitution of the Princely House of Liechtenstein, though notably without consultation from the Landtag of Liechtenstein. Shortly after taking office, Büchel was the subject of controversy due to pushing through a government nomination against the wishes of his own party.
On 14 September 1993, the Landtag passed a motion of no confidence against him following a request by the FBP to do so. The following day, Hans-Adam II dismissed both the government and the Landtag and called for early elections, though notably against the wishes of the FBP. Following the October 1993 Liechtenstein general election, Büchel was succeeded by his deputy Mario Frick.
From 1997 Büchel worked as a lawyer. In 2002, he became Honorary Consul of Russia in Liechtenstein.
Büchel married Elena Medvedeva on 7 May 1998 and they had one child together. He died in on 9 July 2013 in Ruggell, aged 54 years old.
