Political opponents GERB/United Democratic Forces and We Continue the Change/Democratic Bulgaria presented their joint cabinet to the president and have a strong chance of mustering a majority in parliament.
The GERB leader's former ally, Chief Prosecutor Ivan Geshev, has suddenly activated the Prosecution to look into an alleged money laundering scheme involving the ex-PM known as 'Barcelonagate'.
In a dramatic twist, the opposing alliances of GERB/United Democratic Forces and 'We Continue the Change' plus Democratic Bulgaria have agreed to form a government with rotating prime ministers.
Designated Prime Minister Mariya Gabriel was given the mandate to form a government but the GERB party looks unlikely to be able to assemble a ruling majority and has come under fire from Bulgaria's chief prosecutor.
