Poland’s first post-communist president, Lech Wałęsa, has withdrawn a lawsuit against a former union leader who had accused him of being a government agent during the 1970s. Krzysztof Wyszkowski, who was an opponent of the communist regime and a co-founder of the Free Trade Unions of the Coast, had referred to Mr Wałęsa as “Bolek,” his alleged code name in Poland’s communist-era secret service. He also stated that he believed the former leader of the Solidarity trade union had been handsomely rewarded for information he passed on to Poland’s secret police.
