The Financial Services Consumer Panel has appointed former Royal Bank of Scotland lawyer Mark Chidley and former Labour MP Kitty Ussher to the panel.
The pair will begin their three-year terms as members of the panel on 1 February.
Ussher was the Labour MP for Burnley from 2005 to 2010, and served as economic secretary to the Treasury between 2007 and 2008.
In 2009 she resigned from her ministerial position after evidence emerged that she used her second home to avoid paying capital gains tax during the MPs expenses scandal.
She is currently managing director of the research consultancy Tooley Street Research.
Chidley is a solicitor specialising in banking and finance law. From 2002 to 2005 he was director of group legal services at RBS, and since then has been a partner at DLA Piper.
His main focus on the panel will be on issues facing SMEs.
The new members have been appointed following the departures of Debbie Harrison and Fiona Fry.
Consumer Panel chair Sue Lewis says: “I am delighted to welcome Mark and Kitty to the panel. They both bring valuable experience and knowledge of the different ways in which financial services policy can have an impact on consumers, and I look forward to working with them.
“I am also grateful to Debbie Harrison and Fiona Fry for their contribution to the panel’s work over the past years. We wish them all the best for the future.”
