The President of the Czech Republic has banned the U.S. Ambassador from Prague Castle following a public dispute over the former's decision to attend a Russian World War II parade. President Milos Zeman has been criticised by Ambassador Andrew Schapiro over his plans to attend the annual parade in Moscow, marking the Allied win  at the Western front in 1945, despite the crisis in Ukraine. In response to the critique, President Zeman said Ambassador  Schapiro is no longer welcome in the Prague Castle, the seat of presidency. Under attack: Czech President Milos Zeman was criticised by U.S. Ambassador Andrew Schapiro over his plans to attend the annual Victory Day parade in Moscow, despite the crisis in Ukraine . Much to the chagrin of President Zeman, the country's prime minister together with Czech lawmakers are siding with the American. 'I think that the reaction of President Zeman was not adequate,' Prime Minister Bohuslav Sobotka said. 'I would naturally welcome it if the attitude of Mr. President to foreign policy in general was a bit more professional,' Sobotka told the Czech public television on Monday. 'We should be able to communicate with our friends and allies,' Sobotka added. Parliament's lower house speaker, Jan Hamacek, said he thought Zeman was overreacting; the deputy speaker of Parliament's upper house, Premysl Sobotka, said Zeman demonstrated a lack of 'diplomatic thinking.' Harsh reaction: In response to the criticism, President Zeman has banned Ambassador Schapiro from visiting Prague Castle, the seat of presidency. Jan Mlejnek, an analyst, said Zeman's rhetoric was unfortunate and will harm Czech-U.S. relations. In an emailed statement from the U.S. embassy, Shapiro said 'it would be unfortunate for President Zeman to be there as perhaps? the only EU head of state.' Zeman, whose is critical of European Union sanctions against Russia, said he wanted to honor Soviet soldiers who sacrificed their lives to liberate his country in World War II. The Czech presidency is a largely ceremonial post and the government is in charge of foreign policy. Sobotka said he accepted Zeman's explanation for the trip. Shapiro said he regretted that President Zeman felt offended. 'I value a good working relationship with everyone, and I want him to know that my door will be open to him,'? Shapiro said. 'I also want the Czech people to know that the United States government, and the people of America, value our relationship as partners and allies more than ever.' The Moscow Victory Day Parade parade is held on May 9th, and will this year commemorate the 70th anniversary of the capitulation of Nazi Germany in 1945.
