In March 2017, the Chamber of Deputies asked Andrej Babiš, leader of ANO 2011 and Minister of Finance, to explain his finances. In April 2017, he stated in a letter that all his financial activities have always been legal. Speaker of the chamber Jan Hamáček said that he did not consider the explanation sufficient. On 2 May 2017, Prime MinisterBohuslav Sobotka stated that Babiš should resign. Bohuslav Sobotka announced on 2 May that he would resign, leading to the formation of a new cabinet which would not include Babiš. Babiš described Sobotka's decision as a "dirty trick." Lubomír Zaorálek and Milan Chovanec were mentioned as possible replacements for Sobotka as Prime Minister. Sobotka initially planned to submit his resignation to President Miloš Zeman on 4 May 2017, but later decided to resign on 20 May, when Zeman returns from a visit to China. However, Zeman proceeded with the resignation ceremony nonetheless, which was considered a humiliation for Sobotka. Sobotka decided not to resign after the ceremony, and on 5 May 2017 he announced that he would instead dismiss Babiš from government. Sobotka's decision was praised by the leaders of TOP 09, and KDU–ČSL. Petr Fiala, leader of ODS, called for a snap election, and stated that Sobotka's decision would only deepen the crisis. Various politicians stated that the resignation ceremony was shameful for the Czech Republic. Zeman announced on 8 May 2017 that he would not accept Babiš's removal from the government yet, and would make a final decision on his return from China. This decision was criticised by many politicians and lawyers as unconstitutional,, as according to the Czech constitution the president should appoint or dismiss ministers on the request of the Prime Minister. On 10 May 2017, a demonstration of 20,000people was held in Prague against the actions of Zeman and Babiš, and other demonstrations were held around the country. Zeman called a meeting of leaders of coalition parties in Liberec. Sobotka was unable to participate as he had gone to Luxembourg on 10 May, but Zeman met Chovanec, Babiš and Pavel Bělobrádek. Zeman presented the two possible solutions to the crisis as a new election, or a new government without Sobotka or Babiš. ANO 2011 stated that they were prepared to discuss a government that would not include Sobotka or Babiš. ČSSD and KDU-ČSL stated that they would consider a government without ANO.
