Poland's prime minister has announced that his government will dissolve the disciplinary chamber of the country's Supreme Court after the EU condemned the chamber for threatening the "unity of the European legal order."

Speaking to EU officials at the European Parliament, Polish leader Mateusz Morawiecki accepted that the chamber

"did not meet our expectations," agreeing to dissolve the "mechanisms that were introduced. There was a question about the disciplinary chamber of the Supreme Court. Yes. We intend to dissolve it."

The announcement by Poland's prime minister marks the conclusion of a row between Warsaw and Brussels over concerns that its disciplinary chamber made EU law subordinate to national law, sparking a reprimand from European officials.

To prevent future disagreements between member states descending into the row that's broken out between Poland and the EU, Morawiecki called on the EU Court of Justice to establish a chamber that can act as an arbiter for disputes within the bloc.

Poland's leader had pushed back on the EU's threats, by warning that it risked making the bloc a "centrally managed organism," rather than a partnership of member states. He warned:

"Unfortunately, today we are dealing with a very dangerous phenomenon whereby various European Union institutions usurp powers they do not have under the Treaties and impose their will on Member States."

• 'Polexit': Will Poland's 'nuclear strike' on EU's legal order lead to the country quitting the bloc?
• Polexit? Polish court rules EU push for LGBT laws & legal reform incompatible with its constitution
• EU chastises Poland over lack of 'contribution' to Europe, its use as a cash cow
• Polish PM: Poland will never bow to EU's ultimatums
• Poland's new ultra-national government is double trouble for EU and Russia

The encounter, which appears to have occurred without incident, happened amid NATO's annual deterrence exercise Steadfast Noon, taking place this week all across southern Europe.

Aircraft from 14 NATO countries, including the U.S., are taking part in the drill. The U.S. B-1B Lancers operating in the Black Sea are from Dyess Air Force Base in Texas and have been carrying out missions across Europe as part of a bomber task force rotation. The U.S. military regularly flies in international airspace over the Black Sea, and encounters with Russian aircraft have become commonplace. While most intercepts occur without incident, the U.S. has cited instances in recent years of Russian planes flying too close to American aircraft or buzzing Navy ships on patrol.

The Black Sea has been a focal point this week for the Pentagon. Defense Secretary Lloyd Austin is touring the region, making stops in Georgia, Ukraine and Romania.

On Thursday, Austin will attend a NATO defense ministers meeting at alliance headquarters in Brussels.

Turkish authorities have arrested four Russian citizens, one Ukrainian citizen, and one Uzbek national on charges of "military and political espionage" linked to alleged plans to attack Chechen opposition activists residing in Turkey.

The Turkish Prosecutor-General's Office said on October 20 that the men arrested in the cities of Antalya and Istanbul on October 8 are Abdula Abdulayev, Ravshan Akhmedov, Beslan Rasayev, and Aslanbek Abdulmuslimov of Russia; Ihor Yefrim of Ukraine; and Amir Yusupov of Uzbekistan.

The men are also suspected of buying weapons to use against Turkish-based critics of the Kremlin-backed leader of Russia's North Caucasus region of Chechnya, Ramzan Kadyrov.

If convicted, the men face up to 20 years in prison.

Russian officials have yet to comment on the situation.
