       He continued, "We come from different political camps, but I have found out that on important issues, such as security, we can come to an understanding."

       Although the Law and Justice Party came in first in parliamentary elections this October, they failed to secure the necessary majority to form a government.

       Former Prime Minister Mateusz Morawiecki’s government lost a confidence vote on Monday, opening the path for Tusk's ascension via a multi-party liberal bloc.
