Billionaire businessman Michael Bloomberg, the former mayor of New York, has announced his candidacy for US President, saying "the stakes could not be higher".
Mr Bloomberg jumped into the US presidential race today, adding another moderate voice to a crowded field of Democratic contenders seeking to face Republican President Donald Trump in the November 2020 election.
The move represents an about-face for Mr Bloomberg, 77, who had said in March that he would not make a run for the White House.
"I'm running for president to defeat Donald Trump and rebuild America. We cannot afford four more years of President Trump's reckless and unethical actions," said Mr Bloomberg, 77, a media mogul who founded Bloomberg LP.
We cannot afford four more years of President Trump’s reckless and unethical actions.

The stakes could not be higher.
We must win this election.
And we must begin rebuilding America. https://t.co/W6P9uaCyqN
Ranked by Forbes as the eighth-richest American with an estimated worth of $US53.4 billion ($NZ83.3b), Mr Bloomberg will have the advantage of being able to self-finance his campaign and pour millions of dollars into advertising and hiring staff.
His candidacy presents a late challenge to the pack of Democratic contenders near the top in opinion polls - fellow centrists Joe Biden, the former US vice president, and Pete Buttigieg, the mayor of South Bend, Indiana, and prominent liberal US Senators Elizabeth Warren and Bernie Sanders.
Mr Bloomberg has been critical of anti-Wall Street crusader Ms Warren and her plan to tax the super wealthy to pay for programmes ranging from universal healthcare to free college tuition. He will compete with Mr Biden and Mr Buttigieg to become the moderate alternative to the liberal agendas of Ms Warren and Mr Sanders.
He has won allies in the party with his advocacy and philanthropy on climate change and in fighting gun violence, pouring millions into groups pushing for more restrictive gun laws. Mr Bloomberg served as mayor of New York, the largest US city, from 2002 to 2013.
Mr Bloomberg had filed paperwork on Thursday with the US Federal Election Commission to run for president. He already had filed paperwork to be eligible for the Democratic primary in Alabama and four other states with early deadlines for ballot qualification.
He announced earlier in November a $100 million online ad campaign targeting Mr Trump in four battleground states.
Playing catch-up
Mr Bloomberg will face significant disadvantages because of his late start, which means he will be playing catch-up with rivals who have been putting together campaign staffs for months ahead of the state-by-state battle for the Democratic nomination.
To counter that, he plans to pursue the unorthodox strategy of skipping the four states with early nominating contests in February, beginning on 3 February in Iowa, and focus primarily on the states that hold primaries and caucuses starting on so-called Super Tuesday on 3 March.
No winning presidential contender has ever pursued a similar strategy.
Mr Bloomberg already has come under fire from liberal critics who say he would be the wrong choice for a Democratic Party turning against corporate money in politics and dedicated to ending income inequality in America.
He also is certain to face renewed scrutiny over his record as New York's mayor and as the head of his own media company for nearly 40 years.
He apologised this month for New York's "stop and frisk" policy that allowed police to stop and search people on the street, which was decried as racist for overwhelmingly targeting black men. Black voters are a critical Democratic voting bloc.
Mr Bloomberg has also been mocked by some critics for attempting to ban soft drinks sold in cups larger than 470ml in an effort to reduce sugar consumption in the interest of public health amid high rates of obesity in the United States. The proposal was ultimately struck down by New York courts.
Mr Bloomberg will face questions about his decision to run for New York mayor in 2001 as a Republican. He switched to independent before a run for a third term in 2009. In 2018, while weighing whether to run for president, he switched his party registration again and became a Democrat.
At 77, he also will be the second-oldest candidate among the Democrats in a race in which age has been an issue as the party debates whether it is time for a new generation of leadership. Mr Sanders, who took time off from the campaign trail after a heart attack in October, is the oldest at 78. Mr Biden is 76. Ms Warren is 70. Mr Trump is 73.
Public opinion polls show most Democrats do not share Mr Bloomberg's dissatisfaction with the other Democratic contenders. A Monmouth University poll taken in late October and early November found three-quarters of Democrats were satisfied with their choice of candidates and just 16 percent wanted someone else.
