Former Bulgarian ruling party GERB are assembling on their third national conference in Sofia Sunday - a meeting expected to be pivotal for the party.
The congress, to take place at the National Palace of Culture in the Bulgarian capital, is set to discuss the party's strategy for upcoming European Elections 2014.
But it is also planned to vote changes in the GERB's leadership structure, increasing the number of vice-chairs from one to three.
A key question is the fate of current GERB vice-chair and former Bulgarian Deputy-PM and Minister of Interior Tsvetan Tsvetanov.
Tsvetanov's position within the party was shaken after he was charged with mishandling wiretapping while being minister, but more importantly by recent allegations of close ties to controversial media mogul and liberal Movement for Rights and Freedoms MP Delyan Peevski.
GERB delegates however are expected to re-elect former Bulgarian PM Boyko Borisov to lead the party.
Borisov himself has commented that it would be a mistake to depose Tsvetanov at this moment.
