Sylwester Chruszcz, a representative of the party, was quoted by the Polish newspaper Wiadomosci as warning that this spring the Polish-Ukrainian border may well become a "channel for the transfer of illegal migrants to Poland."
"This is why Poland should be prepared start building a wall [to protect itself] from the influx of refugees," he said.
According to Chruszcz, if the Polish government says "no" to his party's proposal, it will be responsible for "a human tragedy because a wave of migrants will rush into Poland."
He also said that the cost of the project will stand at about 225 million zlotys (60 million dollars).
Ukraine has been experiencing a humanitarian crisis since April 2014, when Kiev launched a military operation against independence supporters in the Donbass region.
In September 2014, Ukrainian Prime Minister Arseniy Yatsenyuk announced plans for the construction of a wall on his country's border with Russia.
The 200-million-dollar project entails a barrier about 2,000 kilometers long, which would stretch along Ukraine's actual border with Russia. It would include anti-tank trenches measuring four meters wide and two meters deep, as well as 17-meter tall metal watchtowers, observation posts, alarms, retaliatory weaponry and special border check-points.
