Stronger together

Support for the pro-reform Civic Platform (PO) has surged to 42 percent, while backing for the right-wing ally Law and Justice (PiS) stands at 24 percent. Their combined support, according to Gfk Polonia, tops the two-thirds parliamentary majority needed to change the constitution and push through reforms.

PO has pledged to form a coalition with Law and Justice even if it secures a majority.

Platform's secretary general, Grzegorz Schetyna, said: "We need a coalition because even if the Platform manages to win the elections and gain a majority in parliament, it would be ... with only just above 50 percent of deputies.

"If we want to implement serious reforms, if we want to seriously change the state, we will need a solid partner in parliament and a majority that allows us to govern not just for the first months but for the whole four years." The two parties have pledged to stamp out corruption, cut taxes and labor costs to create new jobs, and tighten fiscal policy, although they remain split over whether Poland should seek to join the eurozone quickly.

Support for Poland's leftist parties has crumbled following a wave of scandals involving their leaders. (Reuters)
