The restructure, led by group marketing director Simon Gulliford, sees retail marketing director Richard Harvey move to a central co-ordinating role.
Harvey will be responsible for ensuring that the bank's three core businesses - personal financial services, business banking and Barclaycard - get the right emphasis and priority.
Andrew Gillespie will take over Harvey's role as retail marketing director.
Gillespie moves from his previous role as director of marketing operations.
Liz Sinclair, campaigns manager, business banking, will take on Gillespie's responsibilities on an interim basis.
The reshuffle also seeks to replace two senior marketers who have both resigned to join utilities companies.
Sara Deeks has been appointed customer insight director, replacing Oliver White who resigned to join Centrica to head customer intelligence last month (Marketing, November 29).
In addition, David Lavarack becomes chief operating officer within Barclays Marketing, taking on an expanded version of the role vacated by Paul Parmenter.
Parmenter left the company to join Powergen as sales and marketing director for its retail business and to oversee a more environmentally friendly repositioning of the brand (Marketing, October 17).
Lavarack will combine his existing responsibilities for internal communications to ensure the marketing and communications departments function smoothly.
In January Gulliford carried out a radical restructuring of marketing.
This saw the marketing directors of Barclays' separate divisions report to Gulliford, instead of to divisional directors.
Gulliford also created a 'marketing centre of excellence' on issues of brand identity, customer insight and marketing operations.
