BN Daybreak: Van Onselen on Joburg; Moeng on Chauke; JSE's 10% risk; Alphabet plunges

Victory Research CEO Gareth van Onselen tells Alec Hogg that no poll gives the DA a majority in Johannesburg, but it should be the largest party - and the closer it gets to 40%, the harder it is to justify shutting it out of coalition talks. Solly Moeng says everything points to Bejani Chauke, the former presidential adviser the Madlanga Commission wants answers from, having acted for Ramaphosa, while stressing nothing is proven. Donald MacKay wants fuller JSE disclosure on a case that could cost 10% of turnover. Bonitas on joining a medical aid early. Plus Alphabet's worst day.
