Solidarity founder Lech Walesa raised the possibility that his union might back its longtime nemesis, Polish leader Gen. Wojciech Jaruzelski, as a candidate for president in upcoming elections.

Addressing a rally Sunday of some 3,000 people following a Mass in St. Brigida's Church in the seaport of Gdansk, Walesa said he believed Jaruzelski had changed since his government banned Solidarity in October 1982."I see Jaruzelski as a different man following our meeting on April 18," Walesa said. "I cannot be guided by emotions and I must be a cool politician now."
