Bulgaria's centre-right ruling party GERB has lost 4.5 percentage points of its electoral support and would attract only 26.6% of voters if the elections were held today, a nationally representative poll conducted by the National Public Opinion Centre (NPOC) showed.
In June, the support for GERB's main opponent, the Bulgarian Socialist Party (BSP), did not change from the previous month and stood at about 18%, state-run Bulgarian News Agency (BTA) cited data from NPOC's survey on Wednesday.
The party of former EU commissioner Meglena Kuneva has emerged as the third most influential political force with 7.5% support.
The Movement for Rights and Freedoms enjoys the support of 6.4% of the respondents, while nationalists party Ataka polled 2.5%, the survey showed.
Former members of the Blue Coalition, the Union of Democratic Forces and the Democrats for Strong Bulgaria, can each count on the backing of about 1.6% to 1.7% of voters.
The poll was conducted among 1,000 people between June 27 and July 3.
