"The Court finds several violations of the Convention and orders the termination of the pre-trial detention of opposition politician Selahattin Demirtas … The Court, therefore, held, unanimously, that the respondent State [Turkey] was to take all necessary measures to put an end to the applicant’s pre-trial detention," the court’s press release read.

According to Sputnik news agency the court said that Demirtas was not promptly brought before a judge and that his right to free elections had been violated.

"The Court found that it had been established beyond reasonable doubt that the extensions of Mr Demirtas’s detention, especially during two crucial campaigns, namely the referendum and the presidential election, had pursued the predominant ulterior purpose of stifling pluralism and limiting freedom of political debate, which was at the very core of the concept of a democratic society," the press release said.

Demirtas was arrested alongside dozens of other party members in 2016 over allegations of having links to the Kurdistan Workers' Party (PKK), listed as a terrorist organization by Ankara.

In September, Demirtas was sentenced to four years and eight months in prison on charges of terrorist propaganda.
