Prague - Former Social Democrat (ČSSD) MP Petr Wolf on Monday received an anonymous letter threatening him with death. Wolf has confirmed the information to Aktuálně.cz.

Wolf, who quit the ČSSD earlier this year citing disagreements over the US radar is convinced the letter was sent in connection to the no-confidence vote to be held today, 22 October.

"You raise your hand for Topol [PM Topolánek] and you won't live, bastard," reads the copy of the letter which has been obtained by Aktuálně.cz.

The MP said that his wife was the one who found the letter in the mail box and that his lawyer has already filed a legal complaint against an unknown perpetrator.

Wolf did not comment on how he will vote today - whether he will support the coalition, or help the ČSSD and the Communists topple the government.

"This goes beyond all limits. These are mafia-like practices. I don't want to accuse anybody though, I don't know who is behind this," Wolf told Aktuálně.cz.

Wolf received death threats in the past. When the parliament voted on agreements concerning the US radar base, he received a number of threatening messages on his mobile phone.
