Oct 24 (Reuters) - Gold inched down on Thursday as investors awaited clarity on Brexit after the European Union delayed a decision on granting Britain an extension, while a weaker dollar provided a floor under prices.
Spot gold fell 0.2% to $1,488.58 per ounce as of 0725 GMT. U.S. gold futures lost 0.3% at $1,491.30 per ounce.
With EU members delaying their decision on whether to give Britain a three-month Brexit extension, Prime Minister Boris Johnson said if the deadline was deferred until the end of January he would call an election by Christmas.
“Even if Brexit goes through, there are enough geopolitical uncertainties to keep gold supported for the next two to three years,” said Hareesh V, head of commodity research at Geojit Financial Services.
“The dollar (index) has corrected from the 99.5 level to 97.2 on a continuous basis for the last two weeks. That is providing some support to prices,” he said.
The dollar index, which measures the greenback against a basket of other currencies, was down 0.1% at 97.396, on track for its second straight session of losses.
