As Apple prepares to launch a new iPhone, Alex Hern explores the privacy scandal around its automated personal assistant, Siri. Plus, Polly Toynbee on why Jeremy Corbyn is preventing Boris Johnson from calling an election

The Guardian’s UK technology editor, Alex Hern, talks to Anushka Asthana about the fallout from his revelations that contractors working for Apple were listening to voice recordings of Siri users in order to grade them. The company’s voice-automated personal assistant had recorded confidential information, illegal acts and even Siri users having sex. It subsequently issued an apology and pledged to change the way Siri is run.

In the run-up to Apple’s annual product launch, Hern discusses why the Siri privacy breach is just one of the company’s many recent challenges.

And: the Guardian columnist Polly Toynbee on why Jeremy Corbyn is trying to stop Boris Johnson having an election.

Apple were approached for comment but declined.
