WARSAW, Aug 11 (Reuters) - Poles will vote on whether they support the privatisation of state companies, Poland's ruling party leader said on Friday, as he announced the first question in a number of referendums likely to be held on the same day as parliamentary elections.

Ruling nationalists Law and Justice (PiS) had initially said they would hold a referendum on a European Union migration deal, in what some analysts viewed as a bid to mobilise their core electorate ahead of an Oct. 15 election seen by many as the most important since the fall of communism in 1989.

"For us, the voice of ordinary Poles is always decisive," PiS leader Jaroslaw Kaczynski said in a video posted on social media platform X, formerly known as Twitter.

PiS say that the main opposition party, the liberal Civic Platform (PO) which is led by Former European Council President Donald Tusk, is subservient to foreign interests, particularly those of Germany.

PO rejects such criticism, and accuses the government of awarding well-paid roles in state-owned firms to people as a way of rewarding them for their support.

"If PiS wants to ask about state-owned companies in a referendum, then Kaczynski should ask Poles whether they support the nepotism, cronyism and theft that is now taking place," PO lawmaker Marcin Kierwinski told state-run broadcaster Polskie Radio 1.
