WARSAW, Feb 1 (Reuters) - The head of Polish refiner Orlen said on Thursday he did not expect to be in his job for much longer after a supervisory board meeting later in the day, as a new government seeks to make a fresh start at state-controlled companies.

"Supervisory board meets today, I've put myself at their disposal and I think the matter will be decided today," Daniel Obajtek told Radio Zet.

"I can't imagine being CEO after Feb. 6."

A shareholders' meeting at Orlen has been called for Feb. 6 to make changes in the supervisory board at the request of the government.

For Poland's new pro-European coalition government, Orlen became a symbol of what it says were efforts by the previous administration to use state-controlled firms for political purposes.

Last month, prosecutors launched an investigation into Orlen's fuel pricing policies ahead of Oct. 15 elections. Orlen and Obajtek deny any wrongdoing. (Reporting by Marek Strzelecki, Pawel Florkiewicz, and Anna Wlodarczak-Semczuk Editing by Mark Potter)
