"The 1988 strikes discouraged the Party leadership and demonstrated its failure to find a solution to Poland’s problems. Combined with Gorbachev’s renunciation of intervention on behalf of Communism, this failure encouraged the leadership to move toward yielding its monopoly of power. On 30 November 1988, there was a televised debate between Lech Walesa and Alfred Miodowicz, the head of the official trade union federation and a member of the Politburo. This was a highly significant step as the television served as a means of controlling the dissemination of opinion. On 6 February 1989, Round Table talks between government and the technically illegal opposition began, with the Church, an institution of great prestige in Poland, playing an important mediatory role. Under an agreement, signed on 5 April 1989, reached against a background of widespread strikes, elections were held in Poland on 4 June. Only 35 per cent of the seats in the lower house, the Sejm, were awarded on the basis of the free vote, the remainder going to the Communists and their allies, but all of these seats were won by Solidarity. This expression of the public will was a dramatic blow to the old order. Communist cohesion collapsed, not least with the Communist Party being abandoned by its hitherto pliant allies. Strikes and other protests meanwhile continued. The new government was headed by Tadeusz Mazowiecki, a member of Solidarity and a Catholic intellectual. He became the first non-Communist Prime Minister behind the Iron Curtain. There was, however, to be a major division between those who endorsed the ‘Round Table’ political settlement of 1989 as a way to avoid bloodshed, and those who criticised it as, allegedly, a compromise providing subsequent cover for ex-Communists to pillage the state."
