Boris Johnson stepped down as leader of the Conservative Party on Thursday, making way for a new prime minister, following an avalanche of resignations by members of his party that eroded his authority and paralyzed the British government.

Speaking to a crowd of supporters and onlookers at the lectern outside 10 Downing Street, Johnson said, “It is clearly now the will of the parliamentary Conservative Party that there should be a new leader of that party and therefore a new prime minister.”

Johnson blamed his party for his downfall, comparing his fellow lawmakers to stampeding animals. “As we have seen at Westminster … when the herd moves, it moves. And my friends, in politics, no one is remotely indispensable,” Johnson said.

There will be no general election. Instead, the next leader of Britain will be chosen in a vote by dues-paying members of the Conservative Party, which will remain in power. Johnson said he would serve until a new leader is in place, which could take six weeks or longer. He appointed a new cabinet of officials to replace all the ministers who had abandoned him, while pledging not to “implement new policies or make major changes of direction.”

Johnson paid tribute to his wife, Carrie, who was watching his speech with their young daughter in her arms. Johnson said they had been through “so much,” but he did not signal any of it was his fault.

“I know there are many people who are relieved, and perhaps quite a few who will also be disappointed. I want you to know how sad I am to be giving up the best job in the world. But them’s the breaks,” Johnson said.

In the end, it wasn’t a policy failure that ended his premiership. It wasn’t a money scandal involving dodgy deals or crony contracts. It wasn’t really a lack of vision. What did in Johnson was his constant bobbing, weaving and ducking. His dissembling. His prevarications over a series of scandals — coronavirus lockdown parties, the refurbishment of his official apartment and the appointment of an ally accused of sexual misconduct.
