WARSAW — The weekend election won by Poland’s right-wing and anti-migrant Law and Justice party has also created Europe’s most right-wing Parliament — one without a single party that is left of center on social issues.
Gone are all of the former communists for the first time since communism fell 26 years ago, as well as a younger generation of politicians focused on women’s rights, gay rights, and the environment.
The 2011 election brought in a transsexual lawmaker, Anna Grodzka, who seemed a striking symbol of how the country was growing more open and progressive. Grodzka will be absent from the new Parliament while some far-right nationalists will be among the newcomers.
In many ways, Poland has long been deeply conservative: abortion laws are strict, the country resists green energy, and refugees are largely unwelcome. Still, there has been a growing acceptance among some for gay rights as Poland comes under greater Western influence.
The expulsion of the left results from several factors: a deeper social shift and the unpopularity of some of the left’s leaders, including Leszek Miller, a former communist.
Left-wing parties took a combined 11 percent of the vote, split between two electoral groups which each fell short of a threshold for getting into the lower house of Parliament, the Sejm.
‘‘The Sejm without the left is like a left-handed person without a left hand,’’ lamented Miller, the head of the Democratic Left Alliance. Miller was prime minister from 2001 to 2004, when the CIA operated a secret prison for terror suspects in Poland, something that has harmed his reputation. Still, most Poles reject him for representing an old ruling order that was often corrupt.
Many commentators, even some sympathetic to left-wing causes, said Miller and another left-wing leader, Janusz Palikot, deserved to be defeated for infighting and other failures.
‘‘Haughtiness, mutual elimination through propaganda, a lack of ideology patched up with cynicism, Miller’s playing on nostalgia for communist Poland, and Palikot’s playing on his own ego, all this has washed away a conviction in Poles that the left wing is useful,’’ columnist Marek Beylin wrote in Wednesday’s Gazeta Wyborcza daily.
A new figure with a more positive image, Barbara Nowacka, headed the United Left coalition, but that move came too late to help, according to Aleksander Kwasniewski, a former left-wing president who called the left’s ejection from Parliament painful.
Younger Poles on the left not tied to the communists are also upset by the setback.
‘‘It’s a sad situation and these will be challenging times for the left,’’ said Adam Ostolski, 37, a co-chairman of the Green Party.
‘‘The left will have to organize change from outside of the Parliament. And Law and Justice will antagonize many groups,’’ Ostolski said. ‘‘I believe we will have a lot of social protests and discontent.’’
The new governing party, Law and Justice, represents this conservative social vision, with its leaders and many of its followers Roman Catholic. It won 37.6 percent of the vote, which translates into 235 seats in the 460-seat lower house, a majority that will allow it to govern alone.
