French presidential favourite Emmanuel Macron has come under fire from both potential allies and his run-off rival Marine Le Pen for acting as if victory next month was already guaranteed.
Mr Macron, a 39-year-old former investment banker, pipped the National Front candidate to first place on Sunday and opinion polls see him comfortably beating Ms Le Pen on 7 May to win the keys to the Elysee Palace.
He took to the stage to thank his supporters in a 15-minute speech with his arms held aloft in a V for victory before going on with aides and a few celebrities to La Rotonde brasserie.
"They were patting themselves on the back with the whole celeb crew," Ms Le Pen remarked while visiting a wholesale market near Paris today.
"It shows that this arrogant cast thinks it's already won and can do what it wants with the country."
A centrist who has never held elected office, Mr Macron would be France's youngest ever president.
He was silent the day after voting, leaving the field open to Ms Le Pen who canvassed support in northern France where unemployment is high.
She attacked Mr Macron for being "weak" in the face of terrorism, days after an Islamist militant killed a policeman on the Champs Elysees boulevard.
Speaking after President Francois Hollande warned earlier in the day against taking victory for granted, Mr Macron said he was more determined than ever to beat Ms Le Pen.
Le Pen's father says campaign was too laid back
"Some have woken up with a hangover because Le Pen is there. I haven't," Mr Macron told reporters after his first campaign trip since Sunday.
"Nothing is won. If things were won, we would not have seen how other elections turned out. I have never considered one minute that it was won. My battle is to defeat Marine Le Pen."
Political leaders from France's two shocked mainstream parties on the right and left have endorsed Mr Macron, including the unpopular outgoing Socialist President Francois Hollande and defeated conservative candidate Francois Fillon.
Yet perceptions of complacency could pose a big risk to Mr Macron's Elysee Palace bid.
Pollsters say a low turnout would favour Ms Le Pen.
