His side-parted hair, his languid speaking style and his baggy double-breasted suits give Mr. Rees-Mogg, a longtime lawmaker, an incongruously prewar air, observers say. His studied eccentricities have inspired memes, online quizzes and T-shirts. For many on the left, however, his highly conservative views on topics including welfare, climate change and abortion are beyond a joke.
And in the years since Britain voted to withdraw from the European Union, Mr. Rees-Mogg, the chairman of a caucus of euroskeptic legislators, has become a force to be reckoned with. His name even came up among possible successors to Theresa May, when the previous prime minister’s Brexit plan began to unravel in Parliament.
In November, after Mr. Rees-Mogg called for Mrs. May to resign, the prospect of his moving closer to power prompted Twitter users to shower him with very British insults. This spring, he capitalized on his growing fame by publishing a volume of history, “The Victorians,” to savage reviews.
Mr. Rees-Mogg has told The New York Times that journalists typically write about him when they have nothing else to report. That may soon change: Mr. Johnson has promised to achieve Brexit by Oct. 31, with or without an agreement, and his House leader will have to pilot the required legislation through a Parliament that has repeatedly voted to oppose no-deal Brexit.
