The fugitive Islamic State leader Abu Bakr al-Baghdadi has appeared in a propaganda video for the first time in five years, recognising the terrorist group’s defeat in the Syrian town of Baghouz. The appearance is only Baghdadi’s second on video, and comes weeks after Isis remnants were ousted from their last organised stronghold in the eastern Syrian desert. The appearance seems designed to acknowledge the loss of the remaining pockets of territory and to demonstrate that Baghdadi is still alive. Written in text on the video, but not spoken by Baghdadi, is a reference to the Easter bombings in Sri Lanka, which killed more than 250 people in churches and hotels.

Labor remains in front in the latest Guardian Essential poll, but only narrowly, with both major parties recording improvements in their primary votes from three weeks ago. Labor is ahead of the Coalition 51% to 49%, which is movement within the margin of error in the government’s favour from the last survey on 8 April, which had Labor in front 52% to 48%. On Monday night Scott Morrison and Bill Shorten faced off in their first televised debate, which provided a numbing spectacle for a very small number of viewers. “The basic dynamic of the 2019 contest was there for all to see,” writes Katherine Murphy. “Morrison really has nothing to say beyond don’t vote for Shorten.

Clive Palmer has promised a $7m trust fund for hundreds of Queensland Nickel workers who lost their jobs but lawyers representing the workers say no details have been given. The lawyers say they are unaware of how the leader of the United Australia party intends to pay outstanding entitlements despite his claim to be establishing the fund. Queensland Nickel was placed in receivership in 2016 with 237 workers made redundant just three days before and hundreds more made redundant as part of the receivership. The liquidator has said Palmer could have advanced the funds to him for distribution but he had not been asked to assist.
