Boris Johnson’s scheduled event in Melbourne on December 7 has been canceled due to unforeseen circumstances, as confirmed by his tour promoter Max Markson. Johnson was set to discuss his new book ‘Unleashed,’ while an event in Sydney the previous day is expected to proceed as planned. Markson clarified that the cancellation is not related to ticket sales and attendees can transfer their tickets or receive refunds. Johnson’s book chronicles his political experiences, including his time as Prime Minister and Brexit negotiations.
