Frontrunner François Fillon faced a crisis in his campaign for the French presidency on Wednesday when prosecutors opened an inquiry for misuse of public funds after a report that his wife drew salary as his assistant but had never actually worked, reports Reuters.
Fillon, a right-wing former prime minister, said earlier he was outraged at the report by the satirical weekly Le Canard Enchaîné which he said showed "contempt and misogyny".
"I see the stink bomb season has started," the 62-year-old told journalists in the city of Bordeaux.
Just hours later, financial prosecutors in Paris said they were opening an inquiry into misuse of public funds relating to the matter.
"Following the publication on January 25th 2017 in the Canard Enchaîné of a story calling Mrs Penelope Fillon into question, the financial prosecutor’s office today opened a preliminary investigation into misappropriation of public funds, misuse of company assets and concealment of these offences," a statement said.
It is common practice for French parliamentarians to employ wives, children and even mistresses in their office.
But the allegation that Fillon's British-born wife, Penelope, was paid for fake jobs - a charge to which he did not reply directly on Wednesday - could undermine his pledge to pursue an honest and transparent campaign and hurt his ratings as the race for the presidency gathers pace.
Fillon is running for the Républicains party in the presidential election on April 23rd and May 7th.
While favorite to win election, he faces a strong challenge from the far-right leader Marine Le Pen, second in the polls, and from independent centrist Emmanuel Macron.
That lead could be affected by how Fillon handles a crisis that risks denting his image as a devout Catholic and family man with a relatively scandal-free record in office.
Polls have for months highlighted voter discontent with the political elite and any hint of improper use of public finances could worsen that perception at his expense.
For the French voter, the case has echoes of similar past scandals over "phantom" jobs.
Alain Juppe, another former prime minister whom Fillon was visiting in Bordeaux on Wednesday, was convicted over use of public funds for fake jobs more than 10 years ago in a case that also led to conviction of former President Jacques Chirac.
Socialist former prime minister Manuel Valls, who hopes to win his party's ticket as presidential candidate, urged Fillon to explain himself on the matter.
"You can't be the candidate of honesty and transparency and not respond," Valls told France Inter radio.
Le Pen usually trades in voter distrust of mainstream leaders but she remained conspicuously silent.
