Turkey Ramps Up Opposition Probes, Keeping Markets on Edge

Turkey launched an investigation into the main opposition party’s leader and arrested more of its mayors, in a widening crackdown that’s likely to stoke investor anxiety over risks to the rule of law and political stability.

Prosecutors started the probe into Republican People’s Party Chairman Ozgur Ozel late Sunday on allegations of insulting the president and threating public officials in a speech in which he criticized the detention of three opposition mayors, according to the state-run Anadolu Agency.
