Bulgaria's centre-right party "Order, Rule of Law and Justice" is to officially take its MEP runners' list to the central election body on Friday.
The candidates as well as the new priorities of the political formation will be presented at a conference immediately after the registration.
Few days ago the leader Yane Yanev announced the first six positions on the party's ticket will be taken by the Libya-held Bulgarian medics.
The nurses, jailed in Judeyda prison and sentenced to death, will occupy the first five spots.
Doctor Zdravko Georgiev, who was the only one acquitted in a HIV trial in Libya yet never allowed to return to his homeland, will be at number six on the list.
Opponents say involving the medics in the upcoming MEPs elections poses a huge risk, as it is not realistic to expect all six medics getting elected, which may give a powerful advantage to Qaddafi.
Another problem is that existing legislation precludes Bulgarian citizens who have not lived in the country for the three months prior to the elections from voting or running for an MEP seat.
The five Bulgarian nurses have spent the past eight years in a Libyan jail and this prevents them from taking part in the upcoming May 20 elections.
