It will also allow Johnson to give his account of his downfall at the hands of his own MPs last summer, in the wake of Partygate and other scandals.
A close MP ally told the Daily Telegraph last night: “Boris Johnson lives inside lots of people’s heads rent-free, so writing a book will be a good opportunity to put his version of events on the table for the record.”
Johnson, 58, a reporter and columnist for the Daily Telegraph for three decades before he entered government, was sometimes seen during his tenure as prime minister clutching a reporter’s notepad, with the date on it, suggesting he would be able to rely on contemporaneous notes for his memoir.
His memoir will come after his former culture secretary Nadine Dorries publishes her account of Johnson’s downfall, titled The Plot.
