South Africa is marking 30 years since its first democratic elections, but the ANC could lose its grip on power due to endemic corruption, record levels of crime and unemployment, and infrastructure problems.

Also in the programme: thousands of people in Australia take to the street to demand action following a surge in violence against women; and a hole in the ozone layer is causing problems for wildlife in the Antarctic.

At a hearing in Washington DC, Donald Trump's lawyers have been arguing that he cannot be tried for his alleged crimes, which include conspiring to overturn the 2020 US presidential election. We ask lawyer Amy Howe what this all means for him and his political future.

Also in the programme: a new transitional council is sworn in to lead Haiti amid continuing violence and chaos; and the so-called 'Pushkin plot' to steal rare books from libraries across Europe and replace them with fakes.

US Secretary of State Antony Blinken is on a visit to China - offering a mixture of friendliness and warnings. We assess US-China relations and ask what, if anything, this visit could change.

Also in the programme: the father of a US-Canadian aid worker killed in Gaza tells us the message he'd like today’s memorial service to send to the world; and the possible dangers of yet another artificial sweetener - one that's hard to avoid if you like soft drinks, cakes or chewing gum.

US President Joe Biden says Ukraine will receive more arms and equipment within the week after the US Senate approved a $60bn aid package. But what difference will this make to the people there?

The US government says allegations that Israeli forces buried more than three hundred Palestinians in a mass grave at a medical complex in Gaza are incredibly troubling. A spokesman for the US state department said it was seeking a response of the Israeli government. Israel's military had earlier rejected the Palestinian allegation as baseless and unfounded.

Also the US Senate is set to vote later today on a major aid package for Ukraine, with its passage all but certain after the House of Representatives approved the assistance with broad bipartisan support. And more than a hundred and thirty people have been arrested during pro-Palestinian demonstrations at New York University in the United States.

A new law in Britain aims to send people arriving on small boats to Rwanda to have their asylum claims processed. The Prime Minister Rishi Sunak said the plan made clear that people who arrived in Britain illegally would not be able to stay. The United Nations says the bill is the wrong solution and sets a dangerous precedent.

Also in the programme: What Ukrainian soldiers on the frontline think about the supply of new American weapons; and Aboriginal people reclaim spears taken from Australia by Captain Cook in 1770. We speak to one of them.

The head of Israel's military intelligence has resigned over his role in failing to stop the Hamas attacks on October the seventh. Aharon Haliva is the highest-ranking official to step down over the assault, in which about twelve hundred people were killed and more than two hundred others abducted. He said his department had not lived up to the task it was entrusted with.

Also in the programme: we look at the impact of Hindu nationalism with our Newshour's correspondent Jamie Coomarasamy reporting from the city of Mathura, in Uttar Pradesh; and we hear why senior officials in Milan want to ban afterhours ice-cream.
