Prime Minister Boyko Borisov has downplayed again any prospect of running for President in this autumn's elections.

He has told journalists he does not see himself as a "uniting figure" for the right-wing electorate.

"I think there are enough people in GERB [the main ruling party, headed by Borisov] who can be uniting and do a good job," the Bulgarian National Radio quotes him as saying.

Borisov has made clear he is not "attracted" by the idea of becoming head of state. "Nor do I consider that I can be as useful there as [I am] now. Moreover, you can see for yourself what is the level of people claiming power at the moment."

Speculation is still mounting over whether Borisov intends to run. Incumbent Rosen Plevneliev, who was endorsed by GERB in 2011, last week said he would not seek another term, while the Prime Minister maintains he would never sacrifice political stability for his own gains.

Earlier this year, he had said he would prohibit any discussions on candidates until the summer.

This week, however, he explained GERB was planning to announce the name of a candidate in September, or right before the start of the presidential campaign.
