The meeting, which spokesman Jiří Ovčáček announced, is due to take place on Sunday afternoon.
ANO will present its presidential candidate on Monday afternoon. Babiš has been consistently vague about his possible candidacy and repeatedly postponed his decision date.
Initially, the ANO movement was supposed to announce its decision this week, but because the chairman was quarantined due to COVID, the deadline was postponed to October 31.
Although Babiš has never confirmed or denied his candidacy, for many months, he has been the main favorite, according to polls. Recently, however, the votes have favored retired general Petr Pavel. Models for a possible second round, then give other candidates a chance against Babiš.
Zeman has repeatedly expressed his support for Babiš’s candidacy in the past.
