Poland

WARSAW, July 2 (Reuters) - Poland's prime minister said on Wednesday his country would complete the projects needed to stage the 2012 European Championship with co-hosts Ukraine.

UEFA president Michel Platini said on Saturday that the tournament may be abandoned if stadiums in Warsaw and Kiev are not ready on time.

"The plan we have accepted and which was accepted by UEFA will be carefully fulfilled by the Polish side," Prime Minister Donald Tusk told a joint news conference with Platini.

Platini, who also met Polish soccer association (PZPN) officials and Sports Minister Miroslaw Drzewiecki, made no comment during the news conference. He is due to visit Kiev on Thursday.

"We guarantee we will deliver on these investments, including the stadium in Warsaw, in line with the schedule," Tusk said.

Both hosts face major infrastructure problems including a lack of stadiums and urgently needed modernisation of airports, road and rail networks.

Long-delayed work on the Warsaw stadium began this year after waves of protests by vendors evicted from the venue -- the biggest bazaar in central Europe until last September.

UEFA has frequently denied it has a contingency plan for the tournament. Platini said last weekend that UEFA would take its final decision on the hosting of Euro 2012 in September.

Eight venues are due to stage the matches, four in each country. As well as Warsaw, the Polish venues are Poznan, Wroclaw and Gdansk. Ukraine's four venues are Kiev, Donetsk, Lviv and Dnipropetrovsk.

UEFA awarded the tournament to Poland and Ukraine in April last year, ahead of rival bids from Italy and a joint bid from Croatia and Hungary.
