hello and welcome to focus on europe. i'm liz shoo. thanks for joining us today! it's peak campaign season in poland. the country is set to elect a new parliament in mid-october. the ruling national conservative party pis is fighting to keep its majority, in a campaign rife with criticism against the eu. the verbal attacks are also aimed at liberal opposition leader donald tusk. he's the former president of the european council and the main challenger in these elections.
