Every top Trump adviser in this photo has now resigned or been fired

Jobs in Donald Trump's administration increasingly appear to come with an expiration date.

The long-rumored departure of White House strategist Steve Bannon has added to a growing list of former aides who have left their jobs less than a year into the Trump administration, demonstrating the turmoil of an administration that has lurched from crisis to crisis.

A photo that began circulating widely in response to news of Mr Bannon stepping down helps illustrate the rate of turnover.

Taken in January, the image depicts Mr Trump encircled by a ring of staffers. Of the six men featured in the image, only two - Mr Trump and Vice President Mike Pence - remain.

First to go was former National Security Advisor Michael Flynn, who was fired after it emerged that he had lied about contacts with Russian Ambassador Sergei Kislyak.

He was followed by former White House Press Secretary Sean Spicer, who resigned the post in June after having generated controversy with some of his statements to reporters.

After that came erstwhile Chief of Staff Reince Priebus, a representative of the Republican Party establishment who was ousted in July amid infighting between different factions in the administration.

And the image does not capture the full extent of the changes that have roiled the administration so far.

Not pictured is short-lived Communications Director Anthony Scaramucci, who survived for less than two week; KT McFarland, who served as a deputy national security advisor; and Rich Higgins, a member of the National Security Council who was removed after penning a conspiratorial memo that warned of dark forces arrayed against Mr Trump.
