Boris Johnson set to be unleashed on GB News on October 6

The memoir has been billed as "a book that shatters the mould of the modern prime ministerial memoir", with the publishers promising to "deliver unmissable cultural and political coverage that will have the nation talking".

Unleashed, penned in Johnson's "inimitable style" according to UK publishers William Collins, is set to be an "honest, unrestrained and deeply revealing book by the politician who has dominated our times" - and will cover all the "big decisions during his time in power".

And Johnson himself has talked up the contents of his much-anticipated memoir, saying his "thoughts on Britain’s future [will] explode over the publishing world like a much-shaken bottle of champagne".

It's not just his October 6 arrival on The Camilla Tominey Show which will make waves, however.

Unleashed comes at an auspicious time for the party which he once led - with both his GB News sit-down and the book's October 10 release date falling right in the midst of the Conservative leadership contest.

As the memoir hits bookshelves country-wide, Tory MPs will be whittling down their choice for leader to just two candidates before the race heads to a membership-wide vote.

Though Robert Jenrick and Kemi Badenoch appear to be out in front ahead of James Cleverly and Tom Tugendhat, just how Conservative MPs will vote remains up in the air.

But the candidates aren't exactly unified on the man whose job they're battling to inherit.

Just last month, Jenrick said he would be "delighted" to include Boris Johnson in his shadow cabinet if he won.

While Badenoch, as she cast her name in favour of Rishi Sunak after Liz Truss's resignation, said: "I'm a fan of Boris - but his return, given all that's happened, would not bring people together".

Cleverly backed a Johnson return at the same time, saying: "I know Boris has learned lessons from his time in No10 and will ensure the focus is on the needs of the country from day one."

And Tugendhat was the first MP to declare his intention to replace Johnson when he stepped down in July 2022, going as far as to decry his former boss as dishonest.
