George Osborne has left his jobs at the London Evening Standard and Blackrock to join financial consultants Robey Warshaw.
The former chancellor of the exchequer served in David Cameron’s cabinet starting in 2010, before leaving politics after Theresa May took power in 2016.
He is currently editor-in-chief at the Evening Standard, having previously served as editor.
At the end of March he will step down from this role, as well as his position as a senior adviser at investment firm Blackrock.
Mr Osborne has been known to hold as many as nine jobs at once. It is not clear if he will be leaving his other appointments ahead of his move.
Robey Warshaw was founded in 2013, and in a statement the company said the former Conservative MP would “significantly enhance the advice we give to clients”.
Mr Osborne said he was proud to be joining an outfit he described as “the best of the best”.
A spokesperson for Robey Warshaw said: “We founded Robey Warshaw eight years ago to help our clients to the very best of our collective abilities and we remain single-mindedly committed to that purpose.
“We believe that George will significantly enhance the advice we give to clients. He brings differentiated experience and expertise to our team from his leading roles in global finance over the past decade.
“We remain hugely ambitious about our company’s future and believe that George will help expand our reach and what we can offer our clients without changing the philosophy or ethos of our firm.”
Mr Osborne was first elected to Parliament in 2001 as an MP for Tatton in Cheshire, and stood down at the 2017 election.
That year he joined the Standard and Blackrock.
Mr Osborne said: “Robey Warshaw is the best of the best, advising great businesses on how to grow, and I’m proud to be joining this first-rate team.”
