Anniversary of Hong Kong's new security measures

Today is the first anniversary of the national security law imposed on Hong by Beijing; many feel they don't recognise their city anymore. We hear from both sides of the debate. Also on the programme, we go to Sudan where there are anxieties that the democratic transition may not last; and we hear about the record breaking heatwave in Western Canada that has caused dozens of deaths.
