Nicolas Sarkozy hit back on Wednesday after being charged with corruption, denying he broke the law and suggesting his political enemies were interfering with the French justice system.
"I have never committed any act contrary to the values of the republic or the rule of law," Sarkozy said after he was charged on three corruption-related counts that threaten to torpedo his hopes of a political comeback.
"I have never betrayed the confidence" of the French people, he added, in extracts of an interview to be aired later by LCI television and Europe 1 radio.
It was to be Sarkozy's first major broadcast interview since he lost the 2012 presidential election to Francois Hollande.
Sarkozy also decried what he called "political interference" in the case -- a suggestion that opponents like the ruling Socialists were behind his legal woes.
"In our country, which is the country of human rights and the rule of law, there are things that are being organised," Sarkozy said.
He said he was "deeply shocked" by the charges, adding that "everything is being done to give me an image that is not truthful."
"The time has come to explain, to have my say," Sarkozy said.
Sarkozy, 59, was hit Wednesday with charges including corruption and influence peddling after he was quizzed for 15 hours by judges investigating an alleged attempt to interfere in judicial proceedings in another case.
After the interrogation in a Paris police station, Sarkozy was put before a judge in the early hours of Wednesday.
The judge accepted the examining magistrates request for the former president to be "mis en examen" -- literally "put under investigation" -- the nearest equivalent of being charged in the French legal system.
Sarkozy's longstanding lawyer Thierry Herzog and senior magistrate Gilbert Azibert were charged with the same offences.
After the hearing, Sarkozy was allowed to return to the Paris home he shares with his ex-supermodel wife Carla Bruni and their young daughter, but he can be recalled for questioning at any time.
He was the first former president of France to be taken into custody in a criminal probe but not the first to be charged with corruption.
Jacques Chirac was convicted in 2011 on graft charges but escaped prison on compassionate grounds due to ill-health.
The charges against Sarkozy carry a theoretical maximum prison term of 10 years but legal experts regard custodial sentences in this case as unlikely.
Hollande said his predecessor must "benefit from the presumption of innocence," while Prime Minister Manuel Valls dismissed suggestions that the former president was being hounded by the Socialist government.
"It's not us who are asking these judges to launch investigations," Valls said.
Investigators suspect Sarkozy tried to obtain information from Azibert about confidential proceedings in an illegal election campaign financing case being considered by one of France's highest courts, and that he was tipped off by a senior figure when judges tapped his phones last year.
Sarkozy has faced virtually non-stop legal battles since he left office.
He had been expected to attempt a political comeback in time for the next presidential poll in 2017, but those plans may now be wrecked.
Sarkozy had been widely expected to stand for the leadership of his UMP party later this year in the first step of the comeback, but such a move would be tricky with charges hanging over him.
Even if the charges are eventually dropped, that is unlikely to happen for several months.
Some of Sarkozy's allies denounced what they saw as a witch-hunt against him. "I question the impartiality of one of the judges who is nourished by hatred," said Nice mayor Christian Estrosi.
Sarkozy's mother-in-law, Italian actress Marisa Bruni Tedeschi, said the move smacked of a "vendetta".
"It's just the right moment to cut off his legs from under him," she told Italy's La Stampa daily. "The move comes precisely at the moment when conditions are being created for him to return as the head of the UMP."
The case was launched after judges looking into the alleged financing of Sarkozy's 2007 election campaign by former Libyan dictator Moamer Kadhafi obtained an unprecedented and controversial authorisation to tap the former president's phones from April 2013.
After four fruitless months they discovered Sarkozy had a secret phone registered under an assumed name, and recordings from that device led to the opening of the case in which he has now been charged.
At its root are allegations that Sarkozy was helped to victory in the 2007 election with up to 50 million euros ($70 million at the time) from Kadhafi and envelopes stuffed with cash from France's richest woman, L'Oreal heiress Liliane Bettencourt.
He dismisses the Kadhafi claims as ridiculous and charges against him in the Bettencourt case were dropped last year.
The Kadhafi investigation is ongoing, as are several other cases in which Sarkozy has been implicated.
Among them is a scandal over the funding of his campaign for re-election in 2012 which resulted in the UMP's leader resigning last month.
