Hong Kong protesters are now in the Legislative Council chamber ... the very heart of the government.

After spraying slogans in Cantonese on the wall behind the President's chair, one protester attempted to hang the British colonial-era flag over the city's crest.

But unable to get it to stay up, they instead spray painted the red Bauhinia crest black and hung the flag off the podium of the Legislative Council President's desk.

Hong Kong was a British colony until 1997, when it was handed back to China.

The British colonial flag has become a regular sight at protests in recent years.
