In Poland there will be a referendum held, alongside the upcoming parliamentary election. There will be four questions asked. The fourth is:

Do you support the removal of the barrier on the border between the Republic of Poland and the Republic of Belarus?

If the majority of voters will vote yes on this question, this market resolves yes, otherwise no.

(Voter turnout doesn't influence the resolution of this market, but can, of course, affect the outcome of the referendum.)
