Poland would like to increase its stake in oil refiner PKN Orlen as a result of the company's merger with rival Lotos, a deputy state assets minister said.

“Poland’s treasury holds only a 27% stake in PKN Orlen. As a result of the (Lotos) transaction we would like significantly increase the treasury’s share in the combined group,” said Deputy State Assets Minister Zbigniew Gryglas.

The state currently holds a 53.19% stake in Lotos.
