Deputy leader of ANO Jaroslav Faltýnek has said he expects a written coalition agreement between ANO and the Social Democrats to be put together over the next two weeks.
Speaking on a Sunday TV debate program, he added that both parties had already agreed on coalition priorities. He said that a similar stage had been reached with the Communist Party.
The emerging minority government is to hoping to lean on tacit support from the Communists in order to secure a majority as well as to pass key legislation. The Communists' Jiří Dolejš said if an agreement was also reached with his party, the Communist Party leadership could ratify the deal in May.
Prime minister in resignation Andrej Babiš, the head of ANO, was among the first to tweet congratulations to the head of the Communist Party Vojtěch Filip, Novinky.cz reports.
Mr Filip, who has led the party for 12 years, was re-elected at the party's congress in Nymburk on Saturday. He narrowly defeated challenger Josef Skála by just 20 votes. His continuation as chairman was not assured after the party's poor results in last year's parliamentary election.
In his tweet, the prime minister expressed the hope the move would pave the way for a new government with majority backing in the lower house. For the first time since 1989, the government will have to rely on the Communists for outside support.
ANO and the Social Democrats are currently negotiating who will be in the minority coalition. The Czech Republic has had a government in resignation since January.
