‘I am the führer. I’m the king’: new book lifts lid on life inside Boris Johnson’s chaotic No 10

Boris Johnson fell out with his former chief adviser Dominic Cummings after growing tired of being treated like a "young and inexperienced king" who needed to be kept in order, Michael Gove has revealed.

The levelling up secretary, who is close to Cummings and was a figurehead of the Vote Leave campaign beside Johnson, said the pair fell out soon after the 2019 election because Johnson no longer wanted to be treated "as a tempestuous thoroughbred, with a strong whip and bridle to keep him in order".

Gove offered the account in a new book, Johnson at 10, by Anthony Seldon and Raymond Newell, which documents the chaos and downfall of the Johnson premiership. It argues that Johnson blamed Cummings and his wife, Carrie Johnson, to disguise his own reluctance to take difficult decisions in Downing Street. Seldon's book states that Johnson described his then fiancee Carrie as "mad and crazy" as he used her as an excuse to avoid confrontations. Ed Lister, Johnson's longtime adviser, said: "He thrives on chaos. They were all his decisions."

A spokesperson for Johnson told the Times, which has serialised the book, that the revelations were "the usual malevolent and sexist twaddle" from the former PM's enemies.

Gove is featured in the book describing how relations between Cummings and Johnson soured soon after the 2019 election victory, which saw them secure an 80-strong majority for the Conservatives. "He gave no other thought to a different way of running No 10 after the landslide than relying still on Dom almost exclusively, though he started to resent the fact that Dom would treat him if not like Jeeves and Wooster, then perhaps like the lord protector with a young and inexperienced king," said Gove.

"After the election, Boris no longer wanted to be treated as a tempestuous thoroughbred, with a strong whip and bridle to keep him in order. Dom could be insulting and rude. Some days the prime minister could laugh it off, but other days he didn't."

Cummings also barred Johnson from meeting Graham Brady, chairman of the 1922 Committee of Tory MPs, it states. "It was a very odd insight into the mentality of No 10 and resulted in a grovelling phone call of apology," said Brady. "Cummings had contempt for our MPs and thought that we should be grateful for being in government, for the general election result, and that our job was now merely to behave."
