PRAGUE (Reuters) - Czech President Vaclav Havel has won re-election to his post in the second round of voting by a joint session of parliament on Tuesday, the chairman of the lower house Miloš Zeman said, announcing the official results. Havel, who did not win the necessary absolute majority of all members of both houses of parliament in the first round earlier on Tuesday, won 99 votes in the 200-member lower house, and 47 in the 81-member upper house the Senate, as the only candidate in the second round, enough for a simple majority of those voting, Zeman said. Many deputies and senators stood to applaud when the result was announced but others remained seated after the closest vote since Havel was first elected president of then Czechoslovakia after leading the non-violent overthrow of the Communist government in 1989. Soon after the result was announced a member of the ultra-right Republican Party, whose leader Miroslav Sládek was eliminated from the first round of voting, stood to protest at the result and said Havel had not been legitimately elected. The statement received boos and whistles from the crowd including a whistle from Havel's scowling wife Dagmar who was seated in the chamber awaiting her husband's arrival to speak. Sládek, a member of parliament, was unable to take part in the election as he is in jail on remand awaiting trail on charges of spreading racial hatred. A Republican plea to allow him to vote from prison was turned down earlier by the joint session of parliament.
