Deflation in Poland?

Time and again one can hear Polish economists voice concern over deflation in Poland's economy. It is true that many food prices have fallen (probably because of Putin's embargo) but utilities (gas, water, electricity) are still quite pricey. So what gives?

Hard work Polonius3, simply hard work for their beloved homeland. You should know the feeling :)

I heard in Trójka yesterday that main reasons for deflation are low gas prices and low agriculural material prices (no idea what the meant, maybe fuel too :))
