Days before a key election and amid war in neighbouring Ukraine, Poland’s two most senior military officers resigned.

Gen Rajmund Andrzejczak, Chief of General Staff, and Gen Tomasz Piotrowski, Operational Commander, did not provide any reason for their decision.

There are reports that the right-wing government is trying to politicize the military ahead of Sunday’s elections.

Despite the claim, the government denies it.

Poland’s opposition and the European Union accuse it of politicizing its judiciary and limiting media freedoms.

Rajmund Andrzejczak resigned Monday, according to his spokeswoman Col Joanna Klejszmit.

“Like any soldier, he is entitled to resign without explanation.”

A resignation was also tendered by Gen Piotrowski.

Polish daily Rzeczpospolita reported that the two generals were at odds with Defence Minister Mariusz Blaszczak over the politicization of the military and a Russian cruise missile that passed over Poland last year.

Gen Piotrowski failed to inform Mr Blaszczak last December that the unarmed missile had entered Polish airspace from Belarus and flown hundreds of kilometers before crashing in a forest.

The missile was discovered by a member of the public only in April, causing considerable embarrassment for the minister.

As far as the Rzeczpospolita report is concerned, Mr Blaszczak and the two generals have not publicly commented on it.

It will be Poland’s “most important election since 1989 and the fall of communism” on Sunday, according to opposition leader Donald Tusk.

Right-wing populist coalition United Right, led by Jaroslaw Kaczynski’s Law and Justice party, is seeking a third term.

After an intensely bitter election campaign, the gap between the right and the centre has narrowed.
