Furthermore, the electoral legislation should provide clear deadlines for candidates to withdraw. Such a deadline should be synchronised with the deadline for the printing of candidate lists and ballot papers. Last-minute withdrawals, such as, for instance, in Hungary in 2018, should be avoided, particularly as they may cause serious confusion amongst the voters. In the 2017 election in Bulgaria, it was even possible that parties withdraw a candidate for their lists after election day, according to ODIHR. This is contrary to international standards.
