Chief Prosecutor Sotir Tsatsarov is to submit early in November demands that seven lawmakers who were sworn in this week be stripped of immunity.

Tsatsarov added Thursday he would also request the immunity of a MEP, the Bulgarian daily Sega reports.

The Chief prosecutors stopped short of giving names, provoking much speculation as to who the lawmakers are.

Different sources suggest former Interior Minister and conservative GERB's key official Tsvetan Tsvetanov and ultra-nationalist Ataka's leader Volen Siderov, who have recently faced trials on various charges.

However, then cannot be prosecuted anymore after being elected to Parliament.

Another possible target will be former socialist party chief and current head of the Party of European Socialists (PES), Sergey Stanishev.

Tsatsarov himself gave fuel to these suggestions by saying, "I think [the names of two] lawmakers are known for certain."

Investigations against lawmakers concern various criminal offenses, he also explained.

Earlier he had announced he would take the step against the three abovementioned politicians, who have recently been tried for illegal wiretapping, hooliganism and having lost seven secret documents, respectively.  

Back in the previous, 42nd National Assembly Tsvetanov, Siderov and Stanishev willfully gave up their immunity in order to be prosecuted, but the first two of them cannot be subject to legal action after becoming lawmakers for another time.

PES' leader also demanded to have his immunity lifted earlier this month, but being MEP he cannot renounce it on his own.

A case against him was halted in end-September after having misfired a number of times over the past years for various reasons.

Tsvetanov's trial was stopped earlier this month due to his new immunity and a hearing to be held a day earlier on the case of Volen Siderov also failed to start for the same reason.
