Czech President Miloš Zeman has caused fresh controversy by describing transgender people as "disgusting" during a television interview.Zeman was responding to questions about a recent law passed in Hungary which bans the public portrayal of homosexuality.The legislation has been harshly criticised by senior figures within the European Union.But during an interview with CNN Prima News on Sunday, the Czech President said that the EU was making a serious mistake by interfering in member states' internal affairs, and defended Hungarian Prime Minister Viktor Orbán."I don't see any reason to disagree with him," Zeman stressed, adding that he can "understand" gays and lesbians."But you know who I don't understand at all?
