Former UK Prime Minister Boris Johnson has cancelled a scheduled event in Melbourne as part of his Australian book tour, citing unforeseen circumstances that require him to return to the UK earlier than planned.

Australian publicist Max Markson confirmed that all tickets for the cancelled Melbourne event are transferable to the Sydney event or fully refundable, denying that low ticket demand was the reason for the cancellation.

Despite the cancellation in Melbourne, Johnson's Sydney event is still on track for December 6, 2024, where he will participate in a 'long lunch' at Doltone House.

At the Sydney event, Johnson is expected to promote his political memoir, 'Unleashed,' which was released by Amazon in October 2024.

The cancelled Melbourne event was intended to promote 'Unleashed,' which details Johnson's political career, including his experiences during Brexit and the Covid pandemic.

In his memoir, Johnson discusses significant decisions made during his premiership, personal experiences, and challenges he faced, including nearly dying from Covid.

Marketed as 'the political memoir of the century,' 'Unleashed' draws on Johnson's background as a journalist and his time in politics.

During the Sydney event, Johnson will reflect on key moments from his time as Prime Minister, including the Covid-19 crisis and the London Olympics.

The Independent, which covers critical issues like reproductive rights and climate change, emphasizes the importance of factual reporting in journalism.

Tickets for the events are priced starting at $295 each, with top-tier options including a three-course meal and a meet-and-greet with Johnson.

Johnson left Parliament in June 2023 following an investigation into the Partygate scandal, which he described as a 'witch-hunt.'

Before becoming Prime Minister in 2019, Johnson served as Mayor of London from 2008 to 2016 and as Foreign Secretary from 2016 to 2018.
