If the Boris Johnson saga has told us anything, it's that nothing is certain in politics and nothing is forever.
BoJo isn't the first once-popular leader to be ousted from power and he certainly won't be the last.

Today FM World News Editor Kate Gregan looks at five world leaders who have fallen on their political sword.
United States - Richard Nixon, August 9, 1974
Five years after he was first elected, Nixon became the first US President to resign from office.
He stepped down after the Watergate scandal, which stemmed from a break-in at the Democratic National Committee office during the 1972 presidential campaign.
United Kingdom - Margaret Thatcher, November 22, 1990
The United Kingdom's first female Prime Minister, dubbed the "Iron Lady" for her personal and political toughness, was forced to resign after 11 years at the helm of the British government.
Thatcher survived an assassination attempt by the Provisional IRA in 1984 but abruptly fell from power at the end of 1990 following an internal leadership struggle.
Australia - Julia Gillard, June 26, 2013
The country’s first female prime minister was sacked by her party just months before an election and replaced by the man she ousted three years prior.
Kevin Rudd overthrew Gillard as leader of Australia's Labor Party following a leadership ballot of Labor lawmakers.
He won by 57 votes to 45.
Iceland - Sigmundur Davíð Gunnlaugsson, April 5, 2016
Iceland’s embattled prime minister became the first major casualty of the Panama Papers.
He was forced to step aside from his office amid mounting public outrage that his family had sheltered money offshore.
Brazil - Dilma Rousseff, August 31, 2016
Brazil's Senate voted to remove President Dilma Rousseff from office for manipulating the budget.
It put an end to the 13 years in power of her left-wing Workers' Party.
Rousseff denied the charges.
61 senators, seven more than the two-thirds needed, backed her removal from office.
