Bulgaria's President Rosen Plevneliev on Sunday voiced his concern about the future of the judicial reform and its real impact on people, days after Justice Minister Hristo Ivanov resigned over Parliament's move to amend the reform.

In an interview with Darik Radio, he acknowledged that, after having appointed two interim governments since 2011, he was not keen to do that for a third time.

His words come as junior coalition partner Reformist Bloc is to discuss on Tuesday its participation in the government following Ivanov's decision to step down.

Plevneliev, however, made clear he was ready to act again if the government resigned, as it did in 2013 and 2014.

He also warned the adopted judicial reform, which fell short of Ivanov's demand to reduce the influence of the prosecuting authority on the judiciary and to make it more accountable before Parliament, was not "the big and deep reform we hoped for".

Commenting on his plans for the presidential elections that are due next year, Plevneliev said it was "early" for him to announce his plans.

Speculation has been mounting over whether Plevneliev is intending to run for a second term.

"When the moment comes for me to be frank with the people, I will come out and will do it," he asserted.

Plevneliev, who had been the proponent and most fervent advocate of a referendum on voting rules, urged Parliament to take the the poll's result into account.

An overwhelming majority voted in October for the introduction of online voting.

However, turnout was below a threshold that would make the result binding on Parliament. Lawmakers are instead obligated to hold a vote.
