Spot gold  was down 0.5 percent at $1,269.20 per ounce at 1157 GMT.

US gold futures  slipped 0.4 percent to $1,272.

Business-friendly centrist Emmanuel Macron won the first round of the French vote on Sunday and opinion polls indicated less support for Le Pen.

The news sent bullion prices to their lowest since April 11 at $1,265.90 in the previous session.

"We've moved from having multiple numbers of positive drivers for gold last week when yields were on the defensive and we had multiple geopolitical risks," said Ole Hansen, head of commodity strategy at Saxo Bank.

"But now with the French election (first round) behind us, there is a bit of a surge of risk-on coming back to the market. The main worry was a strong performance by Le Pen."

Gold is often seen as an alternative investment during times of political and financial uncertainty.

Heightened security risks provided some support. North Korea conducted a live-fire exercise on Tuesday as a US submarine docked in South Korea in a show of force amid concern over Pyongyang's nuclear and missile programmes.

Hansen said gold would trade cautiously this week before a Friday deadline for the US Congress to pass a spending bill funding the government through September or risk a government shutdown.

Holdings of SPDR Gold, the world's largest gold-backed exchange-traded fund, rose 0.17 percent to 860.17 tonnes on Monday. Holdings have risen six tonnes in the past two sessions, indicating investor interest in the perceived safe-haven asset.

But on the technical front, gold faces the potential for a downside correction if and when uncertainty fades, said Jeffrey Halley, senior market analyst at OANDA.

"Gold has resistance at $1,290 and then $1,296, having failed in this area numerous times last week. Below, support lies at $1,265.50 and then the 200-day average at $1,254.80. A daily close below $1,240 would signal a much larger correction could be on the way," Halley said.
