The Bulgarian Socialist Party will not cave in to the pressure of the Party of European Socialists regarding the adoption of the Istanbul Convention while Kornelia Ninova is a chairperson of BSP. This became clear at the 50th Congress of the Bulgarian Socialist Party. Speaking to delegates, BSP leader Kornelia Ninova described the Istanbul Convention as "a threat to Bulgarian society and family".

In her report, Kornelia Ninova reiterated that the BSP will not be forming a coalition with GERB. "Let the elections pass and see which parties will win people's trust and then we can decide with whom we can participate in a government," Kornelia Ninova said.

Kornelia Ninova said she has ideological differences with President Radev, not personal. With regard to the petition for a referendum on the adoption of the Euro initiated by Vazrazhdane party, Kornelia Ninova said that the BSP supports the initiative for a national referendum.

At the beginning of the congress, delegates including former BSP leader Sergei Stanishev booed at Kornelia Ninova. MEP Petar Vitanov demanded that the first item on the agenda should be terminating Ninova's powers as leader of the Bulgarian Socialist Party. However, his proposal was not put to the vote.
