Labor has no intention of changing its policies on negative gearing or dividend imputation, the shadow treasurer Chris Bowen has told Guardian Australia. Facing an intensifying negative campaign from the Morrison government and some parts of the media, Bowen insisted a Shorten Labor government would implement its negative gearing changes in its first term despite a recent cooling in the housing market. “We developed these policies to last for 20 or 30 years. It can’t be changed every year in relation to movements in the market,” he said. In an op-ed, Bowen writes: “Did you know, for example, that the federal government spends $8bn on childcare, but $11.7bn on negative gearing and capital gains tax concessions? ... If we are going to increase our investment in important public services in a fiscally prudent way, we have to recognise that many of the tax concessions that some people have been used to as an entitlement are no longer sustainable and need to be reformed.”

Nearly 20,000 homeless people or people at risk of losing their accommodation were given a demerit point by a private employment services provider in the first three months of the government’s new welfare compliance regime, according to data analysed by Guardian Australia. People issued demerit points often have their payments cut off until they “re-engage” with their provider. Another 94 people with a “homelessness” indicator in their case file were kicked off income support for four weeks due to a “work refusal” or “unemployment failure”. In total, 161 homeless or at-risk welfare recipients were hit with a financial sanction between July and September last year.

Australians living in disadvantaged parts of the country are twice as likely to die from diabetes as those in the wealthiest areas, according to a new research by the Australian Institute of Health and Welfare, which examined how a person’s socioeconomic position impacted their chances of developing or dying from diabetes, chronic kidney disease and cardiovascular disease. Researchers said the findings showed social disadvantage led to higher rates of chronic disease development and a greater likelihood of dying. The most unequal outcome was the death rate for women with diabetes, with women in the most disadvantaged areas 2.39 times more likely to die from it as those in the highest socioeconomic areas. For men, the same ratio was 2.18 times.

Internal Zimbabwean police documents obtained by the Guardian suggest the Zimbabwean army has been responsible for murder, rape and armed robbery during the ongoing brutal crackdown. In more than a dozen investigation reports shared by police officials frustrated at the apparent impunity of the military, a series of alleged attacks are described, including two murders and the rape of a 15-year-old girl.

Jeremy Corbyn and Theresa May have met to discuss the Brexit crisis for the first time this year, in a summit where the two sides disagreed afterwards about whether the prime minister was willing to soften her opposition to a customs union. Corbyn’s camp said the prime minister had shown a “serious engagement in the detail”, while Downing Street said while May had asked questions, she had not shifted her underlying position.

Venezuela’s president, Nicolás Maduro, has accused Donald Trump and a “group of extremists around him” of plotting to topple him in order to seize Venezuela’s oil, and warned he risked transforming the South American country into a new Vietnam. In a Facebook video, Maduro claimed the leaders of the US “empire” were conspiring “to get their hands on our oil – just like they did in Iraq and in Libya”.

Donald Trump has pushed back against America’s top intelligence officials, after they offered international threat assessments to Congress that contrasted sharply with the US president’s own views. Major gaps were evident on North Korea, Iran’s nuclear program, the continuing threat of the Islamic State in Syria and the importance of climate change.

Parts of the United States are bracing for record low temperatures as a blast of Arctic air known as the “polar vortex” grips much of the country. Temperatures could hit -40C in parts of the Northern Plains and Great Lakes – with Chicago colder than Antarctica.

It was hard to open a tab or paper yesterday without seeing the words “Kerri-Anne Kennerley”, “Yumi Stynes” and “Studio 10”. Alex McKinnon unravels how the story unfolded and the sides dug in, looking into the strategies some media outlets employed to make a short segment on a show no one watches the latest battleground for a culture war. “Many of the headlines reporting on the original clip, including the Guardian, have been criticised for framing the issue as Kennerley being called ‘racist’, rather than around the substance of what she said,” writes McKinnon.

The latest release of the consumer price index figures show that inflation growth remains lower than what the Reserve Bank generally wants. The next move in interest rates will more likely be a cut than a rise, writes Greg Jericho. “But whether this rate will come sooner or later depends on how much the bank wishes to spur economic activity, and for the past two years it has been content not to do so more than it already is.”

Speaking to Guardian Australia before the tour of a stage show, Senior Moments, the 78-year-old discusses how she’s embraced ageing – and how life as an Australian celebrity didn’t always come so easy.
