Ex-President Nicolas Sarkozy has said the French justice system is being used for political ends, after he was placed under formal investigation for influence peddling.
In a TV interview, Mr Sarkozy denied committing any unlawful act.
He said the “grotesque” case against him had been intended to humiliate him and harm his reputation.
It’s alleged Mr Sarkozy sought insider information from a judge about an inquiry into illegal campaign funding.
Mr Sarkozy was detained on Tuesday for questioning – the first time a former French head of state has been held in police custody.
The BBC says Mr Sarkozy’s clear accusation is that left-wing elements in the judiciary are trying to bring him down and prevent his return to politics.
