Nov 12 (Reuters) - Gold fell for a seventh straight session on Monday, hitting its lowest in a month as the dollar jumped to 16-month highs on the back of political uncertainty in Europe and the U.S. Federal Reserve's hawkish stance on interest rates.
Spot gold XAU= fell 0.3 percent to $1,206.22 per ounce at 1254 GMT, having touched a one-month low of $1,203.36 earlier in the session. U.S. gold futures GCv1 edged 0.1 percent lower to $1,207.9 per ounce.
"The main driver has been some renewed dollar strengthening... due to political uncertainty in UK and Italy," said Saxo Bank analyst Ole Hansen. "Gold is facing a bit of an uphill struggle due to the dollar strength."

The currency benefited from a broader move away from riskier assets due to U.S.-Sino trade tensions, China's economic slowdown, Brexit uncertainty, and the standoff between Rome and the European Union over Italy's budget plan.
It was also underpinned by the Fed's hawkish stance on interest rates.
The U.S. central bank last week indicated it planned to raise rates next month and remained on track for two more potential hikes by mid-2019 on the back of an upbeat economy and rising wage pressures. U.S. rates tend to boost the dollar and Treasury yields, adding pressure on greenback-denominated, non-yielding bullion.
