Former French president Nicolas Sarkozy has denied the allegation that he used his influence over a probe into his election campaign. He denounced the judicial authorities who put him under investigation.
Sarkozy denied wrongdoing on a French news program on Wednesday.
That was his first public appearance since being released from police custody.
He had been detained for hours for allegations that he obtained information on a trial relating to his 2007 presidential election campaign fraud from a judge in exchange for a new post.
The judicial authorities decided to begin a preliminary process and launched a full-fledged investigation, which may lead to his indictment.
Sarkozy said the judicial authorities wanted to humiliate him and they were politically motivated.
Sarkozy is thought to be planning a comeback in politics after he lost the presidential election in 2012. Analysts say he may be trying to avert political damage by showing his determination to fight the judicial authorities.
