China official in Hong Kong meets pro-democracy lawmakers

China's top representative in Hong Kong has had lunch with pro-democracy lawmakers, in what is being seen as an unprecedented meeting.

Zhang Xiaoming, head of the city's Beijing liaison office, met members of Hong Kong's Legislative Council from across the political spectrum.

This is the first such meeting since Hong Kong's handover to China in 1997.

Some pro-democracy legislators walked out of the lunch after raising concerns about the pace of democratic reform.
