Prime minister David Cameron has appointed a former non-executive board member of the Financial Services Compensation Scheme (FSCS) as a senior adviser on Europe and global issues.
Ivan Rogers will leave the FSCS post he has held since June 2009 and take up his appointment as of January 2012.
Mark Neale, chief executive of the FSCS, said Rogers "contributed hugely" to the organisation.
"I would like to take this opportunity to thank him for all his efforts and advice in shaping the FSCS's direction over the past years and wish him luck in his new role," he said.
Alongside his FSCS role, Rogers was also head of the public sector group at Barclays Capital from 2010-11, and previously filled the same position at Citigroup from 2006-10.
Rogers also worked for former Prime Minister Tony Blair as a principal private secretary from 2003-6.
The appointment follows previous incumbent Sir Jon Cunliffe's move to become the UK's Permanent Representative to the European Union.
