Romania's Prime Minister Marcel Ciolacu resigned after a nationalist candidate's strong showing in the presidential election.
His Social Democrat party will leave the governing coalition, citing a failure to achieve its objectives and a loss of credibility.
The nationalist candidate, George Simion, secured a significant portion of the vote, fueled by public discontent.
Simion's potential presidency is causing concern in European capitals, given his eurosceptic stance and focus on national sovereignty.
