WARSAW (Reuters) - Polish presidential challenger Rafal Trzaskowski tried to rally supporters of other opposition candidates to his centrist cause on Monday, vowing to hold the nationalist government to account ahead of what looks set to be a knife-edge run-off vote.
Incumbent president Andrzej Duda, an ally of the ruling Law and Justice (PiS) party, led the first round of the presidential election on Sunday, but fell short of the 50% needed for outright victory, setting the stage for a run-off with Trzaskowski on July 12.
