BENGALURU (Reuters) - Gold prices edged up on Tuesday, after hitting a two-week high in the previous session, amid political uncertainty over Brexit and as the U.S. dollar held steady.
Spot gold was up 0.2 percent at $1,259.30 an ounce, as of 0357 GMT. In the previous session, the metal touched its highest since June 26 at $1,265.87.
U.S. gold futures for August delivery were nearly unchanged at $1,259.90 an ounce.
"A stronger yuan and slight weakness in the USD has provided support for gold," said National Australia Bank economist John Sharma.
"Also, geopolitical issues such as Britain's confused exit from the European Union and U.S. President Trump's assertion that China was impeding North Korean progress on denuclearisation have provided some support for gold."
The dollar was little changed against a basket of six major currencies on Tuesday after dropping to its lowest since mid-June in the previous session, while the British pound was frail after the departure of two key eurosceptic ministers raised worries about a "hard Brexit."
