While he remains the favorite to become France's next president, centrist candidate Emmanuel Macron's lead over his rivals has narrowed, according to two recent polls.

A Harris Interactive poll for France Télévisions published Thursday had the former economy minister winning 25 percent of the vote, one point less than the last time it was conducted two weeks ago. He maintained a one-point lead over National Front leader Marine Le Pen, who is polling at 24 percent. Macron's predicted share of the vote in the second round run-off vote declined to 62 percent from 65 percent.

Far-left candidate Jean-Luc Mélenchon, who put in a strong showing in a televised debate this week, saw his predicted share of the vote rise to 17 percent from 13.5 percent in the Harris Interactive poll. Mélenchon is now just one point behind embattled conservative candidate François Fillon, whose support remains stable at 18 percent.

An Elabe poll for BFMTV published late Wednesday had Macron winning 23.5 percent of the vote, down from 25.5 percent on March 28-29. Elabe has Macron in a dead heat with Le Pen, also on 23.5 percent, in the first round of the election, scheduled for April 23.
