The Nonpartisan Bloc for Cooperation with the Government (Polish: Bezpartyjny Blok Współpracy z Rządem, pronounced [bɛsparˈtɨjnɨ ˈblɔk fspuwˈpratsɨ z ˈʐondɛm]; abbreviated BBWR) was a "non-political" organization that existed in 1928–35, closely affiliated with Józef Piłsudski and his Sanation movement.
In 1993 Lech Wałęsa, then President of Poland, founded a Nonpartisan Bloc for Support of Reforms, in Polish Bezpartyjny Blok Wspierania Reform, likewise abbreviated "BBWR," which was meant to continue some of the traditions of the prewar organization, and form a group in parliament that explicitly supported the president. The organization achieved limited success in the 1993 elections, capturing 5.41% of the vote.
