Theresa May has appointed John Godfrey as a director of policy in her special adviser team at Number 10.
Godfrey joins the policy unit from Legal & General, where he has been corporate affairs director since January 2012.
Prior to that he was group communications director and previously held roles at Lehman Brothers and Daiwa Capital Markets.
Before entering the City he worked in the Home Office and stood unsuccessfully for Parliament in Scotland in the 1990s.
L&G and Number 10 declined to comment.
Cicero executive chairman Iain Anderson says May’s appointments put financial services on a strong footing to tackle the negotiations over the UK’s exit from the EU.
He says: “With John Godfrey coming out of L&G to head up the policy unit, you have got someone right at the heart of Government who deeply understands financial services because he has been working in the sector for the past decade.
“Then there is David Davis, the secretary of state for Brexit, who clearly believes in Brexit and is very pragmatic. Taking those things together, there is a very good sign already and a good starting point for financial services firms to secure good terms out of the Brexit negotiations.”
