If the presidential election run-off took place on the coming Sunday (June 28), the incumbent president Andrzej Duda would beat his main rival, mayor of Warsaw Rafał Trzaskowski, by a tenth of a percentage point, according to a poll by IBRiS for Wirtualna Polska portal (wp.pl). Another poll by the same pollster, carried out for RMF FM radio and "Dziennik Gazeta Prawna", showed Trzaskowski winning the second round of the vote.
