Billionaire businessman Michael Bloomberg is strongly considering entering the race for the US Democratic Party’s presidential nomination.
The ex-New York City mayor is concerned the current field of candidates is not good enough to beat Donald Trump in the 2020 election, his adviser says.
The 77-year-old is expected to file paperwork this week for the Democratic presidential primary in Alabama.
A total of 17 Democratic candidates are vying to take on President Trump.
Former Vice-President Joe Biden, Massachusetts Senator Elizabeth Warren and Vermont Senator Bernie Sanders are the frontrunners.
Some recent opinion polls have suggested that Ms Warren and Mr Sanders – who are regarded as to the left of Mr Biden – might lose against Republican Mr Trump if either won the party’s nomination.
So far, three Republicans have said they will challenge Mr Trump in the party’s primary contest.
But it is seen as almost impossible that anyone will take the Republican mantle from the president.
