Poland has said the Hungarian ambassador is not welcome at the start of its EU presidency.
Reuters news agency on January 3 quoted a senior official as saying that Poland had decided not to invite the Hungarian ambassador to attend the event that began the European Union (EU) presidency in Warsaw on the same day, after Budapest granted asylum to a former Polish deputy minister who is under investigation for alleged misuse of public funds.
In addition, according to Polish Deputy Foreign Minister for European Affairs Magdalena Sobkowiak-Czarnecka, Hungarian Prime Minister Viktor Orban was also not invited to attend the ceremony at the Warsaw Opera House.
Warsaw reacted angrily when Hungary granted political asylum last month to Marcin Romanowski, a former Polish deputy justice minister who was arrested last July as part of an investigation into misuse of public funds.
Mr Romanowski was quickly released after the president of a European Human Rights Council declared the politician had immunity as a member of the body.
For his part, Mr. Romanowski also denied the allegations against himself.
“When we sent out invitations to guests for the ceremony almost a month ago, we invited the entire diplomatic corps,” Sobkowiak-Czarnecka said in a televised speech on January 3.
However, following the incident involving Mr. Romanowski, Polish Foreign Minister Sikorski decided that the Hungarian ambassador was not a welcome guest at the Warsaw Opera House (where the ceremony took place)” on January 3.
Polish Prime Minister Donald Tusk and European Council President Antonio Costa are expected to speak at the ceremony marking the start of Poland's EU presidency, which each member state holds on a rotating basis for six months. Hungary holds the presidency through the second half of 2024.
Mr Tusk has criticised Mr Orban on issues such as Hungary's stance on the war in Ukraine and Hungarian policies that Poland sees as pro-Russian.
Meanwhile, Mr Orban has told Hungarian media that Mr Tusk's government considers Hungarians to be enemies.
According to Sputnik, Hungary is a member state of the EU and the North Atlantic Treaty Organization (NATO), but is heavily dependent on energy supplies from the Russian Federation.
During the nearly three-year Russia-Ukraine conflict, Hungary has maintained a relatively neutral stance towards both Russia and Ukraine and has repeatedly called for negotiations. Hungary's stance has upset some EU countries.
During his time as the rotating EU presidency, Mr Orban has used the role to try to kick-start his own process to end the fighting through negotiations.
