As Colombia approaches presidential elections next year, the US decision to decertify the country in the war on drugs plays into the hands of its allies on the political right, writes NICK MacWILLIAM

SINCE the fall of the Warsaw Pact, the Communist Party of Bohemia and Moravia (KSCM) has been among the most electorally successful of Europe’s Communist parties — consistently finishing in the top five slots in the Czech Republic’s legislative elections.
All that changed last month — when for the first time since the Nazi-aligned protectorate of 1939 to 1945, the territory which makes up the modern-day Czech Republic found itself with no Communists in Parliament. In the October elections, both the KSCM and the Czech Social Democatic Party (CSSD) finished below the threshold required to enter the Chamber of Deputies.
“It was not only a setback: it’s generally accepted within the party that it was a historical debacle,” says Jaroslav Roman, the head of the KSCM’s international department. “Frankly speaking, people are shocked. We had not expected such a heavy defeat.”
