Watch: Three things you need to know about the mushroom murder trial

The jury in the high-profile murder trial of an Australian woman accused of poisoning her relatives has retired to decide her fate.

Erin Patterson, 50, has pleaded not guilty to four charges - three of murder and one of attempted murder - over a beef Wellington lunch in July 2023.

The prosecution have claimed Ms Patterson knowingly put toxic death cap mushrooms into the home-cooked meal, before lying to police and disposing of evidence.

But the defence argue she accidentally included the poisonous fungi in the dish and only lied because she panicked after hurting people she loved.

Katy Watson, the BBC's Australia correspondent, looks at the three key things to know about the trial.
