The government's spokeswoman said Prime Minister Wlodzimierz Cimoszewicz had accepted the resignation of the State Protection Office boss.
Czempinski, who took over the office in 1993, was in charge when it submitted evidence last December alleging that Oleksy had given information to Soviet and Russian spies.
Oleksy, who resigned last month, maintained his innocence and accused the office's agents of acting on behalf of his political foes.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
