Trump to attend WWII outbreak anniversary in Warsaw - Polish deputy PM

US President Donald Trump's visit to Warsaw to take part in the events marking the 80th anniversary of the outbreak of World War II on September 1 has been confirmed, Polish Deputy Prime Minister Jacek Sasin said on Thursday.

Sasin told online broadcaster wp.pl that the anniversary observances will be held in Warsaw and not in Westerplatte, as originally planned, because "Warsaw is the capital of Poland," where the most important state ceremonies are organised.

He added that Westerplatte, a peninsula in the coastal city of Gdansk, the site of the first battle after Germany's invasion of Poland in 1939, which marked the start of WWII in Europe, will become "an important part of the observances."

"(US - PAP) President (Donald - PAP) Trump we certainly come, this has been confirmed," the deputy PM said, adding that "the information is unofficial but we can say with a high degree of certainty that this visit will take place."

Polish President Andrzej Duda has sent invitations to all leaders of the countries forming the anti-Nazi alliance during World War II and currently their attendance is being confirmed. According to the Polish President's Office, President Duda has invited leaders of all NATO, EU and Eastern Partnership countries, as well as the UN secretary-general to attend.

"We have invited a wide group of world leaders, so we expect and we are convinced that it will be a world event," Sasin said.
