(Updates throughout, adds London dateline) LONDON, Nov 15 (Reuters) - Gold prices rose on Wednesday for a third day, helped by a weaker dollar and falling U.S. bond yields ahead of inflation data later that could influence how quickly the Federal Reserve will raise interest rates. The outlook for U.S. tax cuts that could stimulate economic growth was also clouded after U.S. Senate Republicans created new political obstacles by linking the repeal of a key component of Obamacare to the tax reform plans. "The biggest factor right now shoring up gold is the weaker dollar," said Robin Bhar, head of metals research at Societe Generale. "Also there's speculation that tax cuts could be a long time coming, meaning the Fed will not have to be as aggressive as it might have been." A weaker dollar makes gold cheaper for holders of other currencies, which can stimulate demand, while lower bond yields make gold more attractive by reducing the opportunity cost of owning non-yielding bullion. Higher interest rates meanwhile push bond yields higher and tend to boost the dollar.

Spot gold was up 0.4 percent at $1,285.62 an ounce at

1113 GMT, taking gains this week to 0.7 percent.

U.S. gold futures for December delivery were 0.2

percent higher at $1,285.80. ANZ analyst Daniel Hynes said investors needed a trigger to break gold from a range of between around $1,265 and $1,290 in which it has traded since mid-October. The market was looking ahead to U.S. consumer price inflation after data on Tuesday showed producer prices rose more than expected in October. "This could dictate sentiment leading into the next Fed meeting (in December)," Hynes said. St. Louis Fed President James Bullard said on Tuesday the Fed should keep its benchmark interest rate at current levels until there is an upswing in inflation. Raphael Bostic, one of the newest Fed policymakers, said he backed a December rate rise and would need to see further weakness in inflation and local signs of economic weakness to shelve expectations of gradual policy tightening. On the technical side, resistance was at the 50-day moving average around $1,292 and a Fibonacci level at $1,297.70, said analysts at ScotiaMocatta.

In other precious metals, silver was up 0.7 percent

at $17.13 an ounce.

Platinum was 0.3 percent higher at $928.50 and palladium was down 1 percent at $975.50 an ounce after

touching a two-week low of $974.25.
