The State Prosecutor's Office has forwarded a formal indictment against former MP Beata Sawicka to the Circuit Court in Poznan, western Poland.
The former MP is suspected of incitement and inducement to corruption and of paid protection, accepting financial gain in connection with 'setting up' a tender on a plot of land.
She now faces up to 10 years in prison.
Former MP Sawicka and the mayor of the town Hel, northern Poland, were detained after allegedly taking a bribe in a 'sting' operation prepared by the Anti-Corruption Bureau (CBA) on October 1 last year.
The case catered for a great deal of attention in the Polish media, with Sawicka accusing CBA officers of going beyond their powers. She has also cried and once fainted at a press conference and hinted at thought of suicide.
Recently, Polish daily Gazeta Wyborcza alleged the possible involvement of the American FBI in the corruption case. (mn)
