The Cevipof poll for Le Monde showed Le Pen with 27 percent of votes in the first round, up one percentage point from last month, with Macron stable at 23 percent and Fillon gaining one point to 19.5 percent.

Fillon was initially on 17.5 percent when the poll was initially conducted on March 1-5, but his score improved as pollsters surveyed an additional thousand people after he held a major rally in Paris and his party decided to keep backing him.
