Police firing tear gas have evicted protesters who stormed and ransacked Hong Kong's parliament. Activists had occupied the Legislative Council (LegCo) building for hours after breaking away from a protest on the anniversary of Hong Kong's transfer of sovereignty to China from Britain. The chief executive of Hong Kong, Carrie Lam, held a press conference to reassure people the draft bill that provoked the reaction will not return. Also on the show, on the 40th anniversary of Sony's Walkman cassette player, we look at the device's impact. Dr Steve Caplin is a technology author, and explains the history of the world's first portable music player. Gennaro Castaldo is communications director at the British Phonographic Industry, and tells us how Sony failed to capitalise on the emergence of digital music. And we ask two children to try and figure out how to make a Walkman work. Plus our regular workplace commentator Alison Green explains how to avoid falling into the virtual traps lurking in office email, and we'll have a view on the day's trading in the US with Peter Jankovskis of Oakbrook Investments.
