Michael Bloomberg will not run for president as independent

Former New York Mayor Michael Bloomberg will not run as a third-party candidate for US president.
He had recently considered running as an independent in November's election.
Mr Bloomberg said he was concerned about the unconventional and insurgent campaigns of Republican Donald Trump and Democrat Bernie Sanders.

The owner of the Bloomberg news organisation said his candidacy would risk letting in Mr Trump or his fellow Republican Ted Cruz.
He set out his reasoning in an article on his website on Monday entitled: "The risk I will not take".
Mr Bloomberg said that his run would split the vote. If there was no clear winner in the popular vote, it would create a situation where Congress would choose the president, he said.
"As the race stands now, with Republicans in charge of both Houses, there is a good chance that my candidacy could lead to the election of Donald Trump or Senator Ted Cruz," Mr Bloomberg wrote.
"That is not a risk I can take in good conscience."
In his editorial, Mr Bloomberg criticised the Republican candidates' positions on immigrants and Muslims.
"[Trump] has run the most divisive and demagogic presidential campaign I can remember, preying on people's prejudices and fears," Mr Bloomberg wrote.
Mr Trump, the Republican front-runner, has pledged to deport nearly 11 million undocumented immigrant workers and called for a ban on Muslims entering the US.
Mr Bloomberg said Mr Cruz held many of the same extreme positions but with less "bombastic" rhetoric.
He has long sought the White House and saw a potential opening as Democratic front-runner Hillary Clinton struggled against Mr Sanders in the early races.
Mrs Clinton has since recovered after a series of wins in large southern states.
Formerly a Republican, Mr Bloomberg holds pro-business positions typical of the party. However, he has broken with Republicans on social issues such as gun rights and gay marriage.
He served as New York mayor for three terms from 2002 to 2013. He focused on boosting the business community and improving transport infrastructure.
