HONOLULU (Reuters) - U.S. President Barack Obama will hold a formal meeting with British Prime Minister Theresa May during the G20 summit in China on Sunday, a White House official said.

The meeting is their first since May took office in July.

"The president and the prime minister will discuss a range of bilateral and global issues, and, as close friends and steadfast allies, the United States and United Kingdom continue to enjoy an enduring special relationship," the official said.
