He negotiated with Brandenburgians of Duchy of Prussia in 1635 and led another diplomatic mission to Emperor Ferdinand II and his parliament in Regensburg (Polish: Ratyzbona) in 1636.

As a leader of the pro-Habsburg faction at the royal court, he found an ally in the first wife of Władysław IV Waza, Cecilia Renata of Austria, daughter of Ferdinand II.

He had few friends among the lesser szlachta, whom he mostly disliked and treated the Sejm and regional sejmiks as a 'necessary evil', although he rarely broke any laws.

From 1644 he switched his alignment from pro-Habsburg to pro-French and supported the second marriage of King Władysław with Ludwika Maria Gonzaga.

During his life he became the enemy of Adam Kazanowski and Jeremi Wiśniowiecki, whose power diminished with the marriage between Władysław and Cecylia in 1637.
