Republican presidential candidate Mitt Romney is spending the night in Poland, the final stop on a three-nation tour designed to boost his foreign policy resume with voters back home.

In Gdansk, Romney was endorsed by former Polish President Lech Walesa (lek vah-WEHN'-sah), who led the Solidarity anti-government movement in the 1980s.

Walesa suggested the U.S. needs Romney's leadership to restore its standing in the world. He told Romney: "Be successful."

Walesa's backing was meant to influence Catholics and union members in the U.S. But Solidarity's current leadership distanced itself from the event and criticized Romney as hostile to unions and labor rights.

Romney is set to meet Tuesday with Polish Foreign Minister Radoslaw Sikorski and deliver a speech before returning home.

The trip also took Romney to London and Jerusalem.
