Bronislaw Komorowski has been officially declared the winner of the Polish presidential election. According to election officials the acting president won 53.01 per cent of the vote while rival Jaroslaw Kaczynski got 46.99 per cent. Mr Kaczynski had initially accepted defeat based on an exit poll, but Mr Komorowski's camp remained cautious. Mr Kaczynski is the twin of former President Lech Kaczynski, who died in a plane crash with 95 others in April. This run-off election was held after neither candidate gained more than 50 per cent in the first round last month.
