In this week's episode, Rosie and Katie dig into the Omicron Covid-19 variant that is rapidly spreading around the world. Professor Des Gorman explains what we know so far, before former Prime Minister Helen Clark - who is co-chairing a panel into the global response to the pandemic - discusses how vaccine inequality and loose restrictions are allowing more variants to spread. Then, we look at the new National Party leadership, unrest in the Solomon Islands, and the trial of Jeffrey Epstein associate Ghislaine Maxwell.
