HONG KONG (Reuters) - Hong Kong activists have raised more than HK$5 million (£502,109) in a crowdfunding campaign to take out newspaper ads in a bid to get a controversial extradition bill on the agenda at the G20 summit.

Millions have taken to the streets of the former British colony this month to protest against the bill, that would allow people to be sent to mainland China for trial, plunging the city into political crisis and posing a grave challenge to Communist Party rulers in Beijing.
