Nine To Noon

There are calls for a general election in the UK, where a third prime minister could be put in place in under two months. Following what's been described by the Opposition Labour Party as a "revolving door of chaos", out-going Liz Truss (who claims the dubious record of completing Britain's shortest term as Prime Minister, just 45 days in Number 10) resigned in the early hours of our morning. A new Conservative leader is likely to be in place by this time next week. They need to get the backing of 100 MPs by Monday to enter the race. Pundits are tipping Liz Truss's close contender Rishi Sunak to take over, and Conservative MPs have already openly pledged their support for him. There's also speculation Boris Johnson might tip his hat at it, again. It's reported he's getting similar backing from Tory colleagues. Lynn Freeman is joined by Hugo Gye, Deputy Political Editor of The iPaper, based in the House of Commons press gallery.

The teenage years are difficult enough, without adding the challenges of social media and the impact it has on growing brains. We put a fence children when they're toddlers, so do we need to put a virtual fence around teens' social media use? Kathryn is joined by Kathryn Gray, Head of Middle School at St Margaret's College.

When former international footballers Dr Michele Cox and Maia Jackman hit middle age, like many women, they starting coming up against a range of issues: health concerns, menopause , financial worries, deaths of loved ones and relationship issues. It was a time in their lives when they thought they ought to have it sussed: job, house, thriving kids and relationships and self confidence to sail through it all. Instead, at times they felt like they were hanging on by their fingernails. and they realised that was the case for many women in their age bracket. So they got together to tackle middle-age issues head on - and the result is their book, just published called "Murdering Middleage : Surviving and Thriving in Midlife". Michele Cox played for the Football Ferns and headed Women's Football for NZ Football. She has a PhD in Physical Activity from AUT, as well as an MA in Psychology, and she is the author of five books on sport and excellence. Maia Jackman played for and captained the Football Ferns - she represented New Zealand in the 2007 FIFA Women's World Cup and was selected for the FIFA All Star World XI, the only NZ women's player ever selected.

It's been an extraordinary evening in UK politics, with some pundits saying it looks like a "death spiral" for Prime Minister Liz Truss, who's been in the job for just six weeks. There was total chaos in the Commons during a vote on fracking with reports of Tory MPs being "manhandled" into the voting chamber. The drama continued when Home Secretary Suella Braverman resigned over two data breaches, launching an attack on Liz Truss' premiership in her resignation letter. She's reportedly been followed by Chief Whip Wendy Morton and her deputy.

12 years on from the Pike River mine disaster, the Health & Safety body for the sector says there's still too much tolerance for workplace injury. MinEx is funded by the sector, and tasked with keeping mines, quarries and tunnel projects free from fatalities, injuries and diseases. Chief Executive Wayne Scott says if someone dies in the workplace in New Zealand, too many think 'shit happens' - and move on. He compares this with Australia, where he says workplace deaths are treated very seriously. He speaks with Kathryn, along with Jodi Goodall - a leading Australian figure in health and safety - she was a key contributor to a seminal report in Queensland two years ago which was critical of the state's record of mine and quarrying injuries and deaths.
