Romanian far-right politician Calin Georgescu on Tuesday stopped short of endorsing any other potential candidate after being definitively barred from standing in May's presidential election rerun, adding to uncertainty over who would replace him.

It’s a close question, given the role of Russia and the tender age of the country’s democracy.

Romania’s constitutional court upheld a decision banning presidential front-runner Calin Georgescu from May election, ending the bid that plunged the country into the biggest political crisis since the fall of communism.
