Dan Kitwood/Getty Images(LONDON) — There is a peculiarly British phrase for all those things that split opinions to the extent that no one, no matter how indifferent, has to pick a side.

Named after a particularly divisive condiment to spread on your breakfast toast, the saying goes: “It’s like Marmite — you either love it or you hate it.”

Boris Johnson, the conservative lawmaker who has replaced Theresa May as the United Kingdom’s prime minister, is without a doubt a “Marmite” politician. Although they come from the same party, in both temperament and approach to key political issues, Johnson and May could not be further apart.

Here’s everything you need to know about Boris Johnson, the divisive figure whose primarily goal will be to deliver the Brexit his predecessor so spectacularly failed to achieve.

According to the Daily Telegraph, Johnson once said his chances of becoming prime minister were “as good as the chances of finding Elvis on Mars, or my being reincarnated as an olive.”

After being educated at the elite boarding school Eton College and the University of Oxford, where he was a contemporary of former Prime Minister David Cameron, Boris de Pfeffel Johnson became a political journalist in the late 1980s.

He became prominent mainly for his work at the Times of London and Daily Telegraph newspapers. While at the Telegraph he served as a Brussels correspondent between 1989 and 1994, where he was credited for creating an atmosphere of the skepticism toward the European Union in British public life.

This phenomenon simmered beneath British politics for the next two decades, coming to the boil when the U.K. voted to leave the EU in 2016.

But it was in the late 1990s that Johnson burst into the public eye when he appeared on the satirical panel TV show, Have I Got News for You.

His floppy blonde hair, sense of humor and bumbling persona made him an instantly recognizable public figure.

Yet controversy has followed Johnson wherever he has gone, mainly because he’s been accused of having trouble telling the truth.

In 2001, he was elected as a member of Parliament for the Conservative Party. But three years later, he was sacked from as the Shadow Arts Minister for lying to the party leader about an extramarital affair.

Johnson returned to the front line of politics when he was elected mayor of London in 2008. During his first term as mayor, Johnson oversaw the capital’s responses to such key events as the 2011 London riots and the 2012 Olympics.

He was reelected for a second term in office, proving himself as a charismatic and popular campaigner. Known for his colorful character, Johnson has often turned publicity events into comedic adventures of his own, such as when he got stuck on a zip line while promoting the London 2012 Olympics.

Johnson then led Vote Leave, the official campaign to leave the EU, during the 2016 Brexit referendum in one of the most divisive campaigns in U.K. political history. After the event, where “Leave” won by a margin of 52% to 48%, the campaign was later found guilty of breaching spending laws.

It is that controversy that makes him such a divisive political figure — loved by some, loathed by others. British newspapers are equally divided on how to critique his leadership of the country at such a crucial moment in history.

The Evening Standard has backed him as “the prime minister to turn Britain around,” while the Telegraph, which employed Johnson as a columnist, says he has “infectious optimism that his supporters hope will overwhelm the questions concerning character.”

The Times of London, meanwhile, recently described him as a “philanderer,” albeit one with “remarkable resilience.” It highlighted criticism leveled at Johnson over his personal life and allegedly racist comments in newspaper columns.

The newspaper also pointed to a major mistake during his time as secretary of state for Foreign Affairs over his handling of a case of a British-Iranian woman detained over spying charges in Iran. The woman, Nazanin Zaghari-Ratcliffe, whom Johnson said was there to “teach journalism,” remains in prison to date.

Abroad, his reputation is equally checkered. His time as a young journalist and his Brexit stance have won him few friends among EU leaders, whom he will have to engage with extensively as prime minister.

He has received the endorsement of Donald Trump — crucial in the eyes of many in the Brexit camp, who see an improvement in U.S.-U.K. ties as a key opportunity once it leaves the EU. Trump has even directly compared the two, telling reporters: “He’s a different kind of a guy, but they say I’m a different kind of a guy too.”

Johnson has repeatedly received Trump’s backing and stopped short of condemning the president’s recent comments about “The Squad” as racist in a recent debate.

Throughout his campaign to become leader of the Conservative Party, Johnson has maintained a hard-line stance on Brexit. His position is unequivocal: The U.K. will leave the EU with or without a deal on the Oct. 31, the new deadline for leaving after May failed to pass her Brexit deal through Parliament.

Yet, with most lawmakers intensely fearful of the economic impact of a no-deal Brexit, and his ability to turn his back on previous promises, it is impossible to predict what a Johnson premiership will truly look like.

But one thing’s for sure when it comes to Britain’s “Marmite” candidate: Love him or hate him, politics in the U.K. is set to be invigorated once again.
