Polish Prime Minister Mateusz Morawiecki called an EU embargo on Russian oil was a "triumph of solidarity and unity". After a European Council summit late on Monday, President Charles Michel announced that the bloc's leaders had reached agreement on an embargo on Russian oil imports. "We had a special duty to persuade our partners from the Visegrad Group," Morawiecki said. "And I can say we managed to do that... I can say that today once more solidarity and unity triumphed in the European Council and European Union," he added.
